It can be used for air traffic control surveillance command, surface activity target surveillance, etc. Based on this, controllers can obtain real-time air traffic conditions.ĪDSBRADAR is a professional receiver specially designed for receiving ADS-B signal, which can receive the ADS-B signalġ090MHz ADS-B signal is decoded into information that can be recognized by monitoring software. After processing, the accurate position, altitude, heading, speed, aircraft type, identification code, flight number and other information of the target are obtained, and all the information is updated in real time every second.
ADS-B has higher precision and real-time performance than traditional radar monitoring mode, and can be used as a reference standard.ĪDS-B ground station works with ground omni-directional antenna to receive ADS-B messages in DF17 format broadcast by aircraft and surface vehicles. Therefore, as long as the ground station can decode correctly within the operating range, the positioning accuracy of the aircraft is only related to the accuracy of the target aircraft's own coordinate sensor and altitude sensor, but not to the target range, echo and other factors that affect the secondary radar angle measurement and ranging. After receiving the signal, the ground station and the aircraft in the surrounding airspace decode it to get all kinds of relevant information of the aircraft. It can effectively improve the operational situation awareness of controllers and pilots, expand the monitoring coverage and improve the air traffic safety level, airspace capacity and operational efficiency.ĪDS-B airborne equipment encodes flight number, coordinate, altitude, speed and other information, generates ADS-B message, and broadcasts it through 1090ES data link. ADS-B is the main monitoring technology in the future determined by ICAO.ĪDS-B technology combines advanced technologies such as satellite navigation, communication technology, airborne equipment and ground equipment to provide safer and more efficient means of air traffic monitoring.
