Aircraft monitoring system and method based on GNSS (Global Navigation Satellite System)

Abstract

The invention provides an aircraft monitoring system based on a GNSS (Global Navigation Satellite System). The system comprises an overall treatment onboard end, GNSS onboard equipment and a satellitenavigation central station, wherein the GNSS onboard equipment is used for realizing aircraft positioning; the overall treatment onboard end is used for carrying out integration and framing on aircraft flight information and sending the aircraft flight information to the satellite navigation central station through a Beidou RDSS (Radio Determination Satellite Service) system; the satellite navigation central station is used for carrying out overall treatment on the aircraft flight information to realize aircraft flight display and the grouping of a target aircraft and surrounding aircrafts; and meanwhile, an aircraft flight state is sent to the target aircraft through the Beidou RDSS system.

Description

technical field [0001] The application belongs to the field of aviation technology, and in particular relates to a GNSS-based aircraft monitoring system and method. Background technique [0002] With the continuous growth of China's economy, China's aviation industry has achieved unprecedented development. The rapid development of the entire industry has resulted in an increase in the number of aircraft in the air. The problems of airspace management and aircraft monitoring have gradually become prominent. The monitoring methods of manned and unmanned aerial vehicles are not uniform. The monitoring of general aircraft and civil aircraft is restricted by terrain and altitude. In order to ensure the safety of air transportation, improve airspace capacity and aircraft operating efficiency, it is urgent to adopt new technologies and implement new methods in aircraft surveillance and air traffic management. [0003] The traditional aircraft radar monitoring method has limited ra...

AI Technical Summary

Problems solved by technology

[0003] The traditional aircraft radar monitoring method has limited radar coverage. More than 70% of the area has no radar coverage, and it is seriously affected by terrain and altitude. The communication update frequency is low, the device has a single function and poor versatility

[0004] In civil aviation, the ADS-B-based aircraft surveillance method uses the VHF air-to-ground data link to periodically broadcast the accurate position information of the aircraft. The ADS-B is insufficiently equipped, the cost of airborne electronic equipment is high, and the data update rate is low. The deployment of ADS-B ground stations on the air route is expensive, limited by geographical factors, and the maintenance cost of ground stations is high. Currently, it is not meaningful to promote in UAV and general aviation monitoring
