Embodiment Construction

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0046] Such as figure 1 As shown, an ADS-B monitoring system based on Beidou ground-based augmentation technology provided by an embodiment of the present invention includes an enhanced CORS station, an airborne station communicatively connected with the enhanced CORS station, and an airborne station communicatively connected with the airborne station ADS-B monitoring terminal.

[0047] It should be noted that the full name of CORS is Continuously operating reference stations. It combines GNSS technology with computer technology, network communication technology and other related fields of science and technology to build one or more continuously operating reference stations in a certain area. The benchmark referenc...

Abstract

The invention relates to an ADS-B monitoring system and method based on a Beidou foundation enhancement technology. The system comprises an enhanced CORS station, an airborne station and an ADS-B monitoring terminal. The enhanced CORS station is used to obtain the differential enhancement information of a Beidou satellite, and broadcast and send the differential enhancement information to the outside world. The airborne station is used to receive the positioning signal and the differential enhancement information of the Beidou satellite, and fuse the positioning signal and the differential enhancement information to obtain a high-precision positioning data source. The ADS-B monitoring terminal is used to acquire the positioning data source, display the monitoring information of the airborne station according to the positioning data source, and carry out real-time safety alarm on the airborne station according to the positioning data source and a preset autonomous interval maintaining standard. By using the system, the precision of the data source of the ADS-B monitoring system can be improved, and flight safety can be ensured through taking the autonomous interval maintaining standard as a ground ADS-B monitoring terminal alarm evaluation theoretical basis.

Description

technical field [0001] The invention relates to the field of aircraft monitoring, in particular to an ADS-B monitoring system and method based on Beidou ground-based augmentation technology. Background technique [0002] With the rapid development of the aviation industry in our country, the density of air traffic is increasing, and airspace security issues are becoming increasingly prominent. The US Civil Aviation Administration (FAA) predicts that the risk of air conflicts will increase by 300% in the next 20 years. The emergence of ADS-B has further promoted the development of the aviation industry. The full name of ADS-B is Automatic Dependent Surveillance-Broadcast. Equipment and ground equipment, whose horizontal position information comes from the Global Navigation Satellite System (Global Navigation Satellite System, GNSS), broadcast the obtained information through a variety of ground-air data links, and the adjacent aircraft receive the broadcast information and pr...
