Method for establishing track of broadcast automatic related monitoring target

Abstract

The invention relates to the technical field of navigation and discloses a method for establishing the track of a broadcast automatic related monitoring target. Airborne equipment decomposes position information and transmits messages of the position information to the ground in a broadcast way, wherein the messages are transmitted in the way of odd and even encoding; when ground equipment does not receive the second message and the message which is paired with the first message in an odd and even way, the pair of odd-even messages, i.e. the first message and the second message, are globally decoded to acquire the initial position, when the third message is received, the third message and the initial position which is acquired by globally decoding are locally decoded, a local decoding position is calculated, when the fourth message and the message which is paired with the third message in the odd and even way are received, the fourth message and the local decoding position are locally decoded to acquire a new local decoding position, a global decoding position is calculated according to the pair of odd-even messages, i.e. the third message and the fourth message, and if the global decoding position is equal to the new local decoding position, the position is a position where the track is established.

Description

technical field [0001] The invention relates to the technical field of navigation systems, in particular to a method for establishing a track of a broadcast automatic dependent surveillance target. Background technique [0002] ADS (Automatic Dependent Surveillance) is an emerging surveillance technology recommended by ICAO (International Civil Aviation Organization) in the new navigation system. The so-called Automatic Dependent Surveillance System refers to recording the navigation information obtained by the navigation system, and automatically sending it to the ground receiving and processing system in real time through the satellite data link or the VHF air-ground data link, and then converting the format of the transmission message to the network The data is sent to the ground control center by means of display equipment to provide pseudo-radar images for air traffic management personnel and aviation management personnel to monitor the operating status of the aircraft....
