CNS35H-202-J B3/GPS卫星导航接收机板

The CNS35H-202-J BDS/GPS satellite navigation receiver board adopts the OTrack-128A multi system compatible satellite navigation chip independently developed by Beijing Dongfang Lianxing Technology Co., Ltd., which has independent intellectual property rights. It can receive B3 (I/Q) or B1 (I), GPS L1 navigation satellite signals, with dual antenna input, realizing real-time high-precision 3D positioning, 3D speed measurement, and precise timing of mobile rotating carriers. The positioning result is output through the RS-422 interface according to the specified transmission protocol, while also outputting PPS second pulse signals.

Product Features

The satellite navigation receiver is a timing and navigation component that processes the satellite signals received at BDS B3 or B1, GPS L1 frequency points accordingly, achieving real-time accurate timing, high-precision three-dimensional positioning, and three-dimensional velocity measurement of mobile carriers.
a) It has the function of outputting flight control data through RS-422 serial port to provide three-dimensional position, velocity and other information to the maneuvering carrier;
b) Capable of outputting telemetry data through RS-422 serial port for status monitoring and post analysis;
c) Equipped with power on and reset self-test functions, it can check whether there are faults in the receiver and internal components;
d) With mode conversion function, it can achieve single BDS or single GPS, as well as BDS+GPS mode;
e) Capable of quickly starting positioning by loading ephemeris through RS-422 serial port A;
f) It has the function of resisting narrowband interference.
