It can realize the pseudorange difference and carrier phase difference of GPS and Beidou B3 frequency points.
【Product Introduction and Applications】
The Beidou differential base station is composed of a choke antenna, a base station device, and a post-event differential software. It can realize the pseudorange difference and carrier phase difference of GPS and Beidou B3 frequency points.
The Beidou/GPS differential reference station is used to receive the satellite signals broadcast by the Beidou satellite system and the GPS satellite system, realize self-positioning through acquisition, tracking, demodulation and calculation, and at the same time output and record the original messages broadcast by the Beidou and GPS satellite systems and the observation and measurement data of the satellite receiver in real time for real-time differential and post-differential processing
