1 Product Overview
ADS-B Dual-channel ground station is a new generation of air traffic management equipment suitable for air routes and airport scene surveillance. It consists of a dual-channel multi-channel receiving antenna, a signal processing unit, a data fusion processor, a high-precision timestamp generator, a coding unit, and a data network unit receiving unit, which has the ability to receive ADS-B messages and A/C/S answer messages. PassADS-B ReceiverObtain static information about the target (such as Modes S, flight number, model) and dynamic information (such as position, height, speed, course) to achieve accurate positioning and monitoring of aircraft broadcasting ADS-B messages within a 450-kilometer range. Through the A/C/S message to obtain the target batch number and height information, further through the network of multiple ground stations, using the target to the time difference information of each ground station to achieve the broadcast A/C/S message non-cooperative targets for location identification and tracking monitoring.
