Distress signals take the form of or are commonly made by using radio signals, displaying a visually detected item or illumination, or making an audible sound, from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by grave and imminent danger and requests immediate assistance. Use of distress signals in other circumstances may be against local or international law... Maritime distress signals Distress signals at sea are defined in the International Regulations for Preventing Collisions at Sea and in the International Code of Signals... Aviation distress signals The civilian aircraft emergency frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700. The COSPAS/SARSAT signal can be transmitted by an Electronic Locator Transmitter or ELT, which is similar to a marine EPIRB on the 406 MHz radio frequency. (Marine EPIRBS are constructed so as to float while aviation an ELT is constructed so as to be activated by a sharp deceleration and is sometimes referred to as a Crash Position Indicator/CPI). A "triangular distress pattern" is a rarely used flight pattern flown by aircraft in distress but without radio communications. The standard pattern is a series of 120° turns... Ground distress beacons The COSPAS-SARSAT 406 MHz radio frequency distress signal can be transmitted by hikers, backpackers, trekkers, mountaineers and other ground-based remote adventure seekers and personnel working in isolated backcountry areas using a small, portable Personal Locator Beacon or PLB... https://en.wikipedia.org/wiki/Distress_radiobeacon Distress radio beacons, also known as emergency beacons, PLB (Personal Locator Beacon), ELT (Emergency Locator Transmitter) or EPIRB (Emergency Position-Indicating Radio Beacon), are tracking transmitters which aid in the detection and location of boats, aircraft, and people in distress. Strictly, they are radiobeacons that interface with worldwide offered service of Cospas-Sarsat, the international satellite system for search and rescue (SAR). When manually activated, or automatically activated upon immersion, such beacons send out a distress signal. The signals are monitored worldwide and the location of the distress is detected by non-geostationary satellites, and can be located by some combination of GPS trilateration and doppler triangulation. The basic purpose of a distress radiobeacon is to help rescuers find survivors within the so-called "golden day" (the first 24 hours following a traumatic event) during which the majority of survivors can usually be saved. Since the inception of Cospas-Sarsat in 1982, distress radiobeacons have assisted in the rescue of over 28,000 people in more than 7,000 distress situations. In 2010 alone, the system provided information which was used to rescue 2,388 persons in 641 distress situations... https://en.wikipedia.org/wiki/Flare A flare, also sometimes called a fusee, is a type of pyrotechnic that produces a brilliant light or intense heat without an explosion. Flares are used for signalling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes...

How to communicate on a river
http://rescue3international.com/ In this Rescue 3 international instructional video we discuss whistle signals in the swiftwater environment. A whistle is a vital tool for anyone operating in a water environment. Whistles can be used either to attract attention when in trouble, or as a communication system with specific calls. Swiftwater environments often have high levels of background noise created by the moving water, and in many cases whistle blasts can be heard when vocal communication is not possible. they are also particularly useful during night operations. Rescue 3 International Fox 40 Whistle available at rescue source The ultimate whistle for water rescue. No "pea" to swell or stick. Plastic construction will not rust or fail. This is one of the loudest whistles on the market today! http://www.rescuesourcestore.com/store/Item/WH7905

In Brazil, there are approximately 1,300,000 aquatic rescues per year in the beach, rivers, dams, waterfalls, swimming pools and natural disasters such as floods, flash floods and overflow. Of these 6000 are deaths. The rescue of these victims is mostly done by teams of lifeguards who work together with different experts in the aquatic environment, such as: divers, aircraft crew, fast-water teams, boat crews and pre-hospital and volunteers with aquatic emergency training. The greatest challenge in the aquatic environment is communication between rescue different teams. The standardization of communication is critical to the success and efficiency of each rescue. SOBRASA has been using hand signals between lifeguards since 1997. Recently(2014) the International Lifesaving Federation (ILS) established hand signals to communication at lifesaving position statement - LPS 12. The day-to-day work of lifeguards demonstrated the need for better communication between professionals in aquatic rescue. The aim of this study is to present the similarities and differences in the use of hand signals proposed by ILS and SOBRASA. Methods: The research was based on the analysis of in use signals in several aquatic rescue specialties such as: lifeguards ILS reference service, diving, aircraft rescue service, fast rescue service and craft operators. After collecting all the signs and their meanings in use by all water rescue services, the consensus among experts determined which signals should be included, modified, or excluded to attend everyone in a unique way. Results: All the eight hand signals recommended by ILS were included: Signal 1(modified) - request for assistance to the lifeguard inside the water. It was clarified that only used to request help, but the decision belongs to the lifeguard in the dry area. When the arm is held upright it means rescue aid, and when it is waved it signals that the lifeguard will require full support including advanced life support(ambulance is on call). Signal 2 - Victim submerged (maintained). Last point seen to start the search. Signal 3(ILS modified) - Lifeguards signal that everything is okay or under control. A second gesture was added for greater distances or difficult visual conditions for the same purpose. Signal 4(ILS) - Signs the urgency to make a rescue and point the direction. Signal 5(ILS) - Signals that the lifeguard should move away from the Incident Commander(IC) who is signal at dry land. Signal 6(ILS modified) - Signals that the lifeguard should approach the IC. Added on mode the urgent to come fast(up-down arm). Signal 7 and 8(ILS) - Signals that the lifeguard must move in the direction indicated. Signal 9(included) - Lifeguards question the situation or need to IC instruction. Signal 10(included) - Signals that the lifeguard should stop where it is. Conclusion: All 8 signals recommended by ILS were kept with minor modifications, adding 2 new signals. The modification and creation of this new hand signal was tested in practice in the city of Rio de Janeiro during the last lifeguards graduated, demonstrating clarity, ease of learning and good results in real communication in safety and rescues.

Use of 4G LTE signals in avalanche search and rescue research project
This research report uses quantitative data and analysis to explore the feasibility of using Fourth Generation Long Term Evolution devices that are loaded with an application as a device that can also help save an avalanche victim's life. During the research process we explored the idea of getting an Unmanned Aerial Vehicle to the site of an avalanche quicker than the current search and rescue process as long as the victims have a Fourth Generation Long Term Evolution device plus the loaded app on them that is reporting their position. Going into this project our research team did not know how well Fourth Generation Long Term Evolution signals would propagate through snow. The study of Fourth Generation Long Term Evolution signal propagation through snow was our primary focus in this project in order to determine if it is even "feasible" to use a smart phone as an avalanche rescue beacon.

SART stands for Search and Rescue Transponder. It is a device for locating ships or their survival craft in distress. The SART operates in the 9 GHz frequency band - generating a series of dots when being interrogated by a search craft with an X - Band (3cm) radar. As the search craft approaches to within 1 nautical mile of the SART, the 12 dots change to wide arcs and eventually into complete circles as the search craft nears the SART. For the person in distress the SART provides a visual and acoustic indication when being interrogated. The detection range from a rescue ship to the SART is a minimum of 5 nautical miles, and from a Search and Rescue helicopter up to 40 nautical miles.

This is a video response to Nutnfancy regarding the SPOT satellite tracking system versus 406 PLB's in general. For an outstanding explanation of how a 406 beacon works with the SARSAT and SAR system check out this commercial video... http://www.youtube.com/watch?v=8m78j0TIeVg The main issue with SPOT beacons is the lack of adequate satellite coverage creating excessive delays in receiving SPOT messages (20-40 minutes). While Globalstar is attempting to resolve this issue it will not negate the requirement for Globalstar satellites to have simultaneous view of the SPOT beacon and a suitable ground station. The end result is a lack of world wide coverage, delays in message transmission and inadequate tracking (usually one of the main reason for purchasing the SPOT device). The SPOT beacon itself must also have a clear sky view and tree cover, foliage, and terrain can significantly impact this. SPOT alerts are received by the Emergency Rescue Coordination Centre (IERCC) based in Houston, Texas. A private company, IERCC is responsible for locating someone that can assist you and this may cause delays. Coupled with an annual fee of up to $150, I find the device unsuitable and potentially hazardous. In contrast the 406 PLB's have world wide coverage. Since the emergency signal is captured and held by the search and rescue satellite system and downlinked as the satellite passes a ground station (LUT), there is no area on the earth that is not under surveillance. 406 PLB's (and aircraft 406 ELT as well as marine vessel 406 EPIRBS) also take advantage of two satellite systems, the Low Earth Orbiting (LEO) and the Geostationary Operational Environmental Satellites (GOES). This redundancy can provide almost immediate response to distress signals. While a GPS capable 406 PLB is recommended, it is not essential as the LEO satellites will triangulate the ground position. While it may take up to 40 minutes to confirm the position of a non-GPS equipped PLB, in the mean time attempts will be made to contact the registered beacon owner or emergency contacts. Future plans for SARSAT include a medium earth orbit system (MEOSAR) that will allow for instant triangulation much like the GPS system currently fixes positions. Many PLB's also have a secondary homing frequency on 121.5 Mhz to allow ground, air, and marine searchers another method of homing the signal source. International SAR agencies are generally familiar with PLB's and have pre-arranged response plans and established lines of communication with SAR units. In Canada, PLB's are the responsibility of RCMP or local police. However, if there is any indication the source of the PLB may be involved in marine or air activities, Canadian Coast Guard and/or Canadian Airforce rescue units may be dispatched as well. While the SAR response in other parts of the world may vary, a Canadian Rescue Co-ordination Centre will be advised of any active Canadian PLB anywhere in the world and the Canadian Rescue Co-ordination Centre will begin an investigation as well. The 406 signal is very robust. There have been several activations inside homes, airport hangars, under extensive tree cover and in steep terrain and none have significantly impacted the transmission. In one case that I am aware of children accidentally activated a beacon and while the antenna was not deployed and the PLB was in a basement closet, the 406 signal was still received! While the initial purchase price of a PLB is higher than a SPOT beacon (approximately $250 for a PLB), there is no annual fee. The only real detractors of the PLB models shown are the lack of tracking (although ACR is now producing a PLB with a tracking/OK feature) and the difficulty servicing the batteries. If you can live with those issues, I think PLB's are providing much more value, a more robust signal, and entry into an established search and rescue system that was previously the domain of aircraft and marine vessels. PLB's really are a "world class" device. Disclaimer: These are my personal views and opinions based on my experience with these devices. These are not the views of the Canadian Forces, Canadian Coast Guard, or Canadian Government. I am not an employee of ACR, McMurdo or any other company involved in the sale of these beacons.

Dartmoor Search and Rescue Ashburton River Dart - water rescue training
Working in water at night has its challenges when trying to effect a water rescue. Apart from the obvious reduction in visibility, effective communication becomes harder with the background noise of the water and difficulty in visual signals being seen. This training on the River Dart was designed to get our Swift Water Technicians as well as Mod2 qualified members working together effectively in rigging and positioning our rescue sled and recovering casualties. A very useful training exercise. http://www.dsrtashburton.org.uk/
Satellite Signals Give Hope To Missing Submarine Search
A search and rescue operation for an Argentine navy submarine missing in the South Atlantic with 44 crew members aboard reached its third day on Sunday, after failed satellite calls likely from the vessel raised hopes the crew are alive. Navy said early Sunday morning it would send an aircraft with 21 personnel from Jacksonville, Florida, to assist with the search for the German-built ARA San Juan, which was 268 miles off Argentina’s southern Atlantic coast when it sent its last communication early on Wednesday. http://feeds.reuters.com/~r/reuters/topNews/~3/n3fH4pG-qkI/satellite-signals-give-hope-to-search-for-missing-argentine-submarine-idUSKBN1DJ0GT http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Acoustic Source Localization of Emergency Signals from Micro Air Vehicles
In search and rescue missions, Micro Air Vehicles (MAV's) can assist rescuers to faster locate victims inside a large search area and to coordinate their efforts. Acoustic signals play an important role in outdoor rescue operations. Emergency whistles, as found on most aircraft life vests, are commonly carried by people engaging in outdoor activities, and are also used by rescue teams, as they allow to signal reliably over long distances and far beyond visibility. For a MAV involved in such missions, the ability to locate the source of a distress sound signal, such as an emergency whistle blown by a person in need of help, is therefore significantly important and would allow the localization of victims and rescuers during night time, through foliage and in adverse conditions such as dust, fog and smoke. In this work we present a sound source localization system for a MAV to locate narrow-band sound sources on the ground, such as the sound of a whistle or personal alarm.

Emergency Rescue Equipment- The Signal Mirror (1943)
Prepared by Office Of Strategic Service; WWII Field Photographic Branch Presentation Division. Research and development For The United States Navy. Emergency Rescue Equipment- The Signal Mirror (1943) "Office of Strategic Services - OSS - training film on the use of the signaling mirror for emergency communications." Produced by the OSS for the US Navy. Describes use of the standard ESM/1 Emergency Signaling Mirror, manufactured by General Electric. Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization. https://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Mirror A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. Mirror is correctly pronounced with two syllabols, Mir-ror The most familiar type of mirror is the plane mirror, which has a flat screen urface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image. Mirrors are commonly used for personal grooming or admiring oneself (in which case the archaic term looking-glass is sometimes still used), decoration, and architecture. Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery. Most mirrors are designed for visible light; however, mirrors designed for other wavelengths of electromagnetic radiation are also used... Signaling With the sun as light source, a mirror can be used to signal by variations in the orientation of the mirror. The signal can be used over long distances, possibly up to 60 kilometres on a clear day. This technique was used by Native American tribes and numerous militaries to transmit information between distant outposts. Mirrors can also be used for search to attract the attention of search and rescue helicopters. Specialized signaling mirrors are available and are often included in military survival kits... http://en.wikipedia.org/wiki/Heliograph A heliograph (Greek: Ἥλιος helios, meaning "sun", and γραφειν graphein, meaning "write") is a wireless solar telegraph that signals by flashes of sunlight (generally using Morse code) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter. The heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century. Its main uses were military, survey and forest protection work. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975.

One of a series of Coast Guard films made to educate the public about USCG emergency capabilities, this 1960s film shows a dramatic overview of the search and rescue system. The USCG is here to render help to people in distress using helicopters, planes, land takeoff or flying boats including the Grumman HU-16 Albatross as seen at mark 01:08. At 25:20 the USCGC Cape Newagen, a Cape-class patrol boat, is seen. At mark 01:35, we have life boat stations on seas. They are always alert to any distress call. Another part to the Coast Guard commission is their radio station in which they use to communicate messages through their message centers during emergency actions as seen at mark 2:40. At mark 3:00, we have a scenario on a rescue mission. This is a case of a young couple who are getting an early morning start for a day’s fishing. Their mother expects them at home by 4pm. At mark 3:55, the mother seems a little worried since the couples are late. She dialed the coast guard line from a book and the RCC department picked up. The mother furnishes the information and the search information commence. At mark 5:10, we have a helicopter notified about the case to do a wide area search on the shoreline or sea in a short time. At mark 5:40, we have the patrol guard to search the extensive water front. The message center as seen at mark 6:23 drafts the messages and it’s been sent at the radio deploying units. The operation officer of the coast guard control receives the message as seen at mark 6:50. The patrol receives alert and changes course to the last seen location of the couples. At mark 8:12, we have another patrol leaving the coast guard station for the search before the night totally goes down. At mark 8:42, we have the missing boat as it drifts helplessly on the sea. They have an engine problem and low battery to either call or receive information. At mark 9:45, we have the search been communicated to on the weather condition in the night. Radio contacts were maintained. We have a storm ahead also. At mark 11:05, we see the mother calling to seek real action that the situation is mainly under control and assurance. At mark 12:15, we have reports on the weather conditions been transmitted to the RCC. They concluded that a first light search would be done following the rescue. Storm warning signals are raised at mark 14:15. A coast guard uff bvm plane joins the search as seen at mark 15:40 and a second helicopter follows. The RCC evaluates the information on the search one helicopter searching north and the other south. At mark 17:22, one of the copter went for fuel refilling. At mark 18:15, we see the lost boat. They bring out distress smoke flares after noticing that a craft was around. The information gets to the RCC center that the boat had been found and they call the mother to notify her about the boat that it as been located. The helicopters had helped in the search faster. A reel is been thrown out to help in the rescue. At mark 21:45, the boat is been towed and maneuvered safely to the port. At mark 22:15, we see the mother heading towards the coast guard center. The tow line is released to let the boat drift down through the dark. At mark 22:30, we have the family been united with one another. The boat is then boarded by the coast guard to determine the cause of the crisis. The search and rescue operations are very important. Also certain safety precautions should be observed by boat owners as seen at mark 23:15. Engeneerian is important as lots of boat defaults are caused by engine problems. Signaling apparatus should be around at all times with knowledge onto how its been used. Because a boat is been rescued, 2 helicopters, 3 life boats, one cutter and a U F plane is been used to search an area of 4000 square miles. There are emergency numbers of coast guards on books and they have various apparatus for the job. A careless boat operator contributes to like 35% of rescue missions carried out. Learn what is required of you and do it. The Grumman HU-16 Albatross is a large twin–radial engine amphibious flying boat that was used by the United States Air Force (USAF), the U.S. Navy (USN) and the U.S. Coast Guard (USCG), primarily as a search and rescue aircraft. Originally designated as the SA-16 for the USAF and the JR2F-1 and UF-1 for the USN and USCG, it was redesignated as the HU-16 in 1962.

African Partnership Flight - Search and Recovery 101
Members of the Ghanaian air force put together a movement search and rescue signal during the first African Partnership Flight March 13 in Accra, Ghana. The movement SAR signal shows that people in need of rescue have relocated. During this APF event participants put together movement, assistance and reflective signals, and they also practiced using signaling mirrors. The USAF shared ground-to- air signaling tactics used to signal SAR aircraft with Benin, Ghanaian, Nigerian, Togolese, and Senegalese Air Forces to help strengthen all participants capabilities and exchanges ideas on how to improve USAF capabilities.

How to Train Your Dog with Hand Signals

Train your dog with hand signals to be sure you understand one another. Step 1: Train with hand and verbal at first Combine hand signals with verbal directions at first. Use only a one-word command when training your dog. To have the dog sit, for instance, don't be inconsistent and confuse the dog with the words "sit down" Step 2: Teach sit Slip a hand under the dog's collar and tease them with a treat until they sit; after which, say "sit" and reward the pooch. Stand up, waving one open hand past the dog's face toward your chest, palm up, as you say it again. Quit talking once the motion is recognized. Tip Since dogs are more responsive to signals, they will be easier to train if you limit verbal directions to simplify things. Step 3: Tell them to stay Condition the dog to stay, one of the hardest commands, pulling each time you command with a leash. Return the dog to the same spot when they disobey. Once you have cooperation, hold your palm toward their nose, as if you're a policeman telling someone to stop. Step 4: Practice “Stay” Back away while holding the hand toward the dog, to test. After getting seconds of compliance, drop the hand and give the praise, 'good dog!' They respond to praise, so continue the same cycle until the dog will stay put on a hand signal alone. Step 5: Instruct “Come” Order the dog to "come" holding a hand out like a handshake, bending your elbow to pass the hand across your chest, and the dog's face, and slowly touching your opposite shoulder. Reinforce with positive tones, finally just using the signal. Step 6: Make them lay Make the dog lay down by first using the leash to lower the dog whenever you say "down," perhaps using a treat as a lure. Repeat, replacing the word with a hand motion, laying the palm down on the floor in front of the dog's eyes. Step 7: Start higher Emphasize, in cases where the dog may not be picking up the signal, that you want the dog down by starting with your hand higher. Drop it abruptly at a 30-degree angle from your body. The dog will respond quickly. Tip The palm down should be used exclusively for the "down" signal, instead of for the "sit" command, to avoid confusing a dog. Step 8: Train with repetition Continue to practice all of the commands, using hand signals when walking, before feedings, or when letting the dog in from relieving themselves. This is not about control but canine communication and building habits. Did You Know? Some 300 Labradors, golden retrievers, and Newfoundlands trained by the Italian School for Rescue Dogs were credited with saving more than 100 lives on Italy's beaches, including a dozen halfway into 2010.

Life-Saving Satellites
http://www.facebook.com/ScienceReason ... NASA GOES: Life-Saving Satellites - Search And Rescue: Saved By A Weather Satellite --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- When weather struck ... His only chance for survival, was a signal sent to space just before he was dragged under water. Denniss emergency beacon activated and transmitted a distress signal triggering a chain reaction into an intricate Search And Rescue Satellite-Aided Tracking System that has been saving lives since 1982. NASA, NOAA, the U.S. Air Force, and the U.S. Coast Guard are working together to eliminate this search, out of search and rescue to reduce the amount of time to reach victims in distress. There have been over twenty seven thousand people saved by this system, many of which were been done by the GOES satellites. The GOES (Geostationary Operational Environmental Satellites) weather satellites have the ability to constantly oversee a large area of the Earth, and send real time data to users. Every country that can see the GOES satellite is able to pick up the distress down link. The beacon goes of and sends a message out to whoever can hear it. A GOES satellite if its in view of the beacon will see it and then itll take that message and just relay it, repeat it back down to the ground. If the distress is from an old beacon, which does not transmit its own location, then the GOES satellites provide an immediate alert. Then you wait until the POES satellite flies over and gives you the location. These beacons can be encoded with GPS location and thats been an advancement over the last fifteen years. This allows us to not only speed up the rescue coordination effort but the chances of survival for someone in a distressed environment is pretty significant. That information thats coming from, directly from the distress beacon to the satellites is the one key link that we have to actually find out where something is happening and hopefully again if the beacon is registered, tells us who that beacon belongs to. Technology developed by NASA and operated by NOAA led to a quick coast guard response and a challenging navy rescue. People take for granted the risks the rescue personnel, so anything we can do to minimize the area that they have to cover, the amount of hours they have to fly, is better for them. A new system called the Distress Alerting Satellite System or DASS is currently being tested successfully at the NASA Goddard Space Flight Center in Maryland. The Distress Alerting System will carry a search and rescue repeater on a complete constellation of satellites. In the case that the GPS systems that means twenty-four satellites will be lessening for victims all over the surface of the Earth. With the new system the information that we get will be quicker, it will be more accurate from the instant that there is a distress happening out there. Once the system is fully operational the ultimate goal of eliminating the search out of search and rescue will be accomplished. • http://www.nasa.gov/goes-p • http://goes.gsfc.nasa.gov/text/goesfaq.html .

Titanic Contacts the Carpathia (The Last Signals)
Click here for the full film: http://www.youtube.com/watch?v=7-AWbrdNo58 http://www.http://tomlynskeyfilms.com/ 12:25 am, April 15. The Titanic, not desperate yet, first establishes contact with the Carpathia via Marconi telegraph. No other ship, apart from the Mount Temple, is able to offer help. Getting in touch with the Carpathia gives Harold Bride and John Phillips hope that rescue is possible. The Carpathia was the first on the scene- hours after Titanic had sunk- too long after to save anyone in the water. This clip features the moment the rescue ship is reached. On the left is the scene in the Titanic's wireless room. The right is the Carpathia. This is using footage from my upcoming Titanic film "The Last Signals", which focuses on the two telegraph operators of the ship, Harold Bride and John Phillips.

East Sooke SAR flight in UAV with upset in poor weather
UAV Search and Rescue mission. Flight captured some video and covered some ground but then experienced difficulties mainly attributed to heavy cloud conditions with heavy rain shower activity which caused a weak GPS signals to the aircraft. The UAV needs at least 6 reliable satellites to find is position in space. Once the PF noted the UAV's confusion he selected fail safe mode, the UAV held its position and auto landed as it was programmed to do. The on board GPS did record the position where it landed and in Pilot and SAR team was able to recover it. Even as it hit a tree branch as it auto landed, the aircraft was undamaged. The PF also noted that the deteriorating weather seemed to have a negative affect on the useful range of the wifi repeater and thus the video transmission. As a result, of this operation, 2 extra points are included in the pre take off check list including a check of at least 6 satellites over 90 seconds, and a test of the HL (home lock) function before a flight is continued. The UAV firmware has also been updated to RTH (Return to Home) feature in the even the PF selects Failsafe of radio signal is lost.

Latest News of Malaysia Missing Plane: Signal of missing plane detected, Vietnamese media report
KUALA LUMPUR, Malaysia — A Malaysia Airlines Boeing 777-200 carrying 239 people lost contact over the South China Sea early Saturday morning on a flight from Kuala Lumpur to Beijing, and international aviation authorities still hadn't located the jetliner several hours later. The plane lost communication two hours into the flight in Vietnam's airspace at 1:20 a.m. (18:20 GMT Friday), China's official Xinhua News Agency said. Vietnamese website VN Express said a Vietnamese search and rescue official reported that signals from the plane were detected about 120 nautical miles (140 miles; 225 kilometers) southwest of Vietnam's southernmost Ca Mau province. Malaysia Airlines said it was working with authorities who activated their search and rescue teams to locate the aircraft. The route would take the aircraft from Malaysia across to Vietnam and China. Related PHOTOS Malaysia Airlines flight loses contact Statement from Malaysia Airlines ''Our team is currently calling the next-of-kin of passengers and crew. Focus of the airline is to work with the emergency responders and authorities and mobilize its full support,'' Malaysia Airlines CEO Ahmad Jauhari Yahya said in a statement. ''Our thoughts and prayers are with all affected passengers and crew and their family members,'' he added. All countries in the possible flight path of the missing aircraft were performing a ''communications and radio search'', said John Andrews, deputy chief of the Philippines' civil aviation agency. Fuad Sharuji, Malaysian Airlines' vice president of operations control, told CNN that the plane was flying at an altitude of 35,000 feet (10,670 meters) and that the pilots had reported no problem with the aircraft. He said the aircraft's last communication was over the South China Sea between Malaysia and Vietnam. Flight MH370 departed Kuala Lumpur at 12:41 a.m. Saturday (16:41 GMT Friday) and had been expected to land in Beijing at 6:30 a.m. Saturday (22:30 GMT Friday), Malaysia Airlines said. The plane was carrying 227 passengers, including two infants, and 12 crew members, the airline said. Passengers were from 14 countries, including 153 from China, 38 from Malaysia, seven Australians and four Americans. At Beijing's airport, authorities posted a notice asking relatives and friends of passengers to gather to a hotel about 15 kilometers (9 miles) from the airport to wait for further information, and provided a shuttle bus service. Zhai Le was waiting for her friends, a couple who were on their way back to the Chinese capital on the flight. She said she was very concerned because she hadn't been able to reach them. A woman wept aboard the shuttle bus while saying on a mobile phone, ''They want us to go to the hotel. It cannot be good!'' Yahya, the airline CEO, said the 53-year-old pilot, Zaharie Ahmad Shah, has more than 18,000 flying hours and has been flying for Malaysia Airlines since 1981. The first officer, 27-year-old Fariq Hamid, has about 2,800 hours of experience and has flown for the airline since 2007. Malaysia Airlines' last fatal incident was in 1995, when one its planes crashed near the Malaysian city of Tawau, killing 34 people. Malaysia Airlines has 15 Boeing 777-200 jets in its fleet of about 100 planes. The state-owned carrier last month reported its fourth straight quarterly loss. The 777 had not had a fatal crash in its 20-year history until the Asiana crash in San Francisco in July 2013. All 16 crew members survived, but three of the 291 passengers, all teenage girls from China, were killed. Associated Press writers Chris Brummitt in Hanoi, Vietnam, Didi Tang and video producer Aritz Parra in Beijing, China, contributed to this report.

24   epirb
EPIRB Emergency Position Indicating Radio Beacon Mostcommon epirb operates on 406MHz using polar orbiting satelites. Its the simplest means of comunication, providing only one way of communication. The EPIRB transmits a distress signal and a satallite system calculates distress position and relays coordinates to nearest rescue centre. Most 406MHz EPIRB also transmits signal on 121.5MHz that allows search and rescue units to obtain a radio bearing of the EPIRB. Epirb is attached to the vesselwith a hidrostatic release, that lets it float free in case the vessel sinks. It is very important to register your EPIRB with the appropriate national authority, so that when you activate your epirb, your vessel details, such as name, size and type of vessel are known immediately to the RCCs.
