Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] An ADS-B position calculation method based on a space-borne scene. The ground control center first receives the monitoring data from the space-borne ADS-B, judges whether the data type is position information, and then uses the reference point calculation method or parity after identifying the position information. The joint calculation method completes the calculation of the position information, so as to obtain the flight position of the aircraft in time. figure 1 is the flow chart of the algorithm, according to figure 1 To elaborate on the algorithm:

[0024] (1) Determine the location message type

[0025] First, the ground control center receives the monitoring data sent by the on-board ADS-B, and judges whether its type is a position message type. If it is not a position message type, return to wait for the next piece of monitoring data and judge its da...

Abstract

The invention discloses an ADS-B position calculation method based on a space-borne scene. The ground control center first receives the monitoring data from the space-borne ADS-B, judges whether the data type is position information, and passes the reference point after identifying the position information. The calculation method or the odd-even joint calculation method completes the calculation of the position information, so as to obtain the flight position of the aircraft in time. Finally, it is judged whether to update and store the reference point information according to the track point filtering situation. Compared with the current ADS‑B position calculation method, the present invention realizes the step-by-step judgment of position information, and has the advantages of high recognition rate, high calculation accuracy and high efficiency.

Description

technical field [0001] The present invention relates to the field of civil aviation surveillance, in particular to an ADS-B position calculation method based on a space-borne scene, mainly through the space-borne ADS-B receiver to obtain the flight state information of the aircraft, and the ground control center uses the CPR algorithm to calculate the position of the aircraft. The latitude and longitude location information. Background technique [0002] ADS-B (Automatic Dependent Surveillance-Broadcast), also known as Automatic Dependent Surveillance-Broadcast, is a surveillance technology widely used in air traffic control systems. It has been widely used in the field of civil aviation surveillance worldwide. . The ADS-B system continuously broadcasts the location information (latitude, longitude and altitude), identity and category information, and working status of the aircraft in the surveillance area through a specific wireless data link. The aircraft and the ground c...
