Description
Technical field
The present invention relates to a kind of aircraft Automatic dependent surveillance broadcast (Automatic Dependent Surveillance-Broadcast, be called for short ADS-B) equipment, especially relate to a kind of ADS-B airborne equipment and Beidou function start and stop method with Beidou function.
Background technology
Beidou satellite navigation system (BeiDou (COMPASS) Navigation Satellite System) is the Chinese independent development capability of implementing, the GPS (Global Position System) of independent operating, is listed as the whole world four large GNSS systems with the GALILEO of GPS of America, Russian GLONASS and European Union.The Big Dipper area navigation pilot system of building up for 2003, claims again the Big Dipper system, can provide active location, time service and short message communication service (abbreviation Beidou function) in China and surrounding area; The number of users that this system can be held is limited.Within 2012, build the area navigation positioning system that covers Asia-Pacific region, passive location, time service and short message communication service can be provided to Asia-Pacific region; To the year two thousand twenty, build up GPS covering the whole world.Passive location number of users can be unlimited, and short message communication service-user number remains limited.
Automatic dependent surveillance broadcast (ADS-B) is to utilize vacant lot, absolutely empty data communication to complete a kind of blank pipe new technology that air traffic situation monitors and information is transmitted, automatically expression does not need the inquiry on manual operation and ground, relevant expression information is all based on airborne equipment, monitor and represent to provide position and other data for monitoring, broadcast represents not for specific user, but periodically sends to any one to have the user of suitable equipment.ADS-B airborne equipment application function can be divided into transmission (OUT) and receive (IN) two classes.ADS-BOUT refers to that airborne transmitter sends the various information of aircraft with certain cycle, comprise aircraft identifying information (ID), longitude and latitude, highly, speed and course etc. (being called for short ADS-B information).Transmission is the basic function of airborne ADS-B equipment.The ADS-B information that land station sends by receiving airborne equipment, monitors air traffic situation, plays the effect that is similar to radar.ADS-B IN refers to that aircraft receives the ADS-B information of other aircrafts transmissions or the information that land station's service equipment sends, for unit provides operation support.ADS-B IN can make unit on passenger cabin traffic information diaplay device, " see " operation conditions of other aircrafts, thereby improves the air traffic context-aware of unit.
But the distance sending and receiving information of ADS-B equipment is limited, has exceeded land station's range of receiving or just cannot monitor at the aircraft of the region navigation of not setting up land station.The structure > > (< < forest fire protection > > the 2nd phase in 2007) of document < < northeast aerial forest fire protection air traffic control system (ATCS) proposes " information terminal of the Big Dipper and ADS-B signal generator are installed aboard simultaneously ", " when boat is protected aircraft flight, the information exchange that the Big Dipper obtains ADS-B at that time for No. is automatically crossed double satellite receiver and is transferred to Big Dipper integrated information service platform ".Because system of the Big Dipper is applied towards all trades and professions, and the number of users that it can hold and channel capacity are limited, and moving multi-user can affect its reaction velocity simultaneously, and the scheme that therefore will promote document proposition on a large amount of aircrafts is inconvenient.
