Description
Technical field
The invention belongs to avionics system communication field, be specifically related to a kind of emergency position indicating beacon based on the Big Dipper, be a kind of emitter that can independently position in the case of aircraft distress, the location and the Field Force that are mainly used in aircraft search and rescue.
Background technology
Location after aircraft distress accident and search and rescue, be the key subjects of aircraft industry needs solution, and in recent years, international and national repeatedly occurs aircraft distress to have an accident, and all cannot be carried out effectively positioning and be quickly carried out rescue, causes heavy losses to personnel and property.2009, Air France AF447 flight was murdered in overhead, the Atlantic Ocean, and Air France spends a large amount of funds and time for finding black box, and first three search expends 17,000,000 pounds altogether, and finally once looks for black box to spend 7,600,000 pounds, the nearlyest 2 years.2014, Malaysian Airlines System claims Boeing 777-200 aircraft being loaded with 239 people with a frame out of touch with Control Centre, Ma Hang has been started up rescue and contact mechanism finds this aircraft, but Missing Aircraft does not send more specific location information, so investigator cannot judge what situation it there occurs.
The aviation flight recorder (black box) installed on passenger plane has 2, can record aircraft flight data and cockpit voice.Black box is the firmest, is resistant to fiercely impact and high temperature hot flame during air crash.But, black box does not has radio transmission apparatus, it uniquely can externally send the parts of signal is subsea beacon (UnderWaterBeacon, ULB).The acoustic signals that black box sends under water can only be received in water by sonar, but its investigative range only has several kilometers, and relative boundless sea equals to " looking for a needle in a haystack ".
Therefore after aircraft distress accident, aviation accident place is accurately positioned significant, in civil aviaton, also becomes, for positioning the emergency position indicating beacon (EmergencyLocatorTransmitter, ELT) of search and rescue, the equipment that must install.Emergent localizing emission equipment belongs to avionics communication system, it it is an aviation multipurpose urgent indicating positions transmitter that can work alone, launch radio signal after being mainly used in aircraft distress, help Search and Rescue Organization to determine position the rescue work of rapid deployment distress personnel of aircraft in distress.
According to the description in " RTCA/DO-204A406MHz meet an urgent need localizing emission equipment lowest performance specification ", ELT can be divided into four classes: AF (fixed pattern), AP (dismountable type), AD (Automatic-expanding type) and S type (lifesaving type) by using type.AF type ELT is all set up aboard before and after aviation accident, is mainly used in the location of accidental site；AP type accident before fastening aboard, in danger after can easy removal, typically there is auxiliary antenna；AD type ELT is installed aboard before aviation accident, works during accident or after being automatically separated after accident；S type ELT is to pull down from aircraft and carry with after accident, and general floatability is at the water surface.
According to International Civil Aviation airworthiness standard requirement, after 1 day July in 2008, any approval carrying 19 people must install 1 ELT equipment to get off the plane, can be lifesaving type be also Auto Power On type；Must install more than 2 ELT equipment during the 20 above aircraft flight of people, wherein 1 must be Automatic-expanding type ELT.If performing the flight across water task must install lifesaving type urgency localizing emission equipment.
For the problems referred to above, international and domestic tissue is devoted to the development of lifesaving radio-location technology always, solution the earliest uses radio beacon position technology, utilize the ELT rear radio beacons signals launching characteristic frequency in danger of this technology, recorded the orientation of Radio Beacon by the principle of radio direction finding.According to GJB2414-95 " aviation lifesaving radio station general specification ", when searching and rescuing aircraft flight height at 3000 meters, beacon range is 150 kilometers.Owing to beacon emissions power is little, typically in hundreds of milliwatt, and ambient radio interference is big, and practical function distance and direction finding precision are the highest.
Scheme two is the global satellite search and rescue system (COSPAS/SARSAT) developed jointly by Canada, France, the U.S. and the former Soviet Union, is the important component part of the Global Maritime Distress and Safety Syst that current International Maritime Satellite Organization carries out.This system uses low-altitude satellite to be sea including polar region, the whole world, land and aerial provide distress alerting and positioning service, so that person in distress is succoured timely and effectively, COSPAS-SARSAT COSPAS-SARSAT is in being successfully applied to world wide in substantial amounts of search and rescue in danger.The ELT utilizing this system is merely able in the case of aircraft damaged condition is little carry out, its emergency mode is to send a signal to COSPAS-SARSAT satellite system, and satellite system sends " the aircraft SOS " of 406MHZ to local satellite user terminal (LUT).Without suitable LUT, satellite system can store 406MHZ " aircraft SOS ", until there being suitable LUT.Follow the tracks of search and rescue satellite and receive that satellite forwards in danger show a beacon signal and data, then decode, calculate and provide beacon identification code and position data, revise the orbit parameter of satellite simultaneously the most in real time, alert data and the statistical information of beacon are given and searched and rescued Mission Control Center (MCC) accordingly.This simply sending signal rather than oneself particular location, solution is the problem of " Who Am I ", then calculates accident spot by ground control centre according to the signal received, may bring error.
COSPAS-SARSAT COSPAS-SARSAT uses low-altitude satellite to be sea including polar region, the whole world, land and aerial provide distress alerting and positioning service, due to the satellite orbit of this system relatively low (850～1000km), the area ratio Geo-synchronous fixed statellite that single satellite covers the earth is little.Thus, in the case of current six satellite operation, for target in danger, there is certain waiting time, especially near region of the equator, the time interval that two satellites leap areal is the longest up to 1.5 hours.And this system is by state's outer control, its distinctive encryption mode is open to China, is not suitable for China lifesaving location under specific circumstances and military use.
