LX203-3 Beidou Navigation Module

The LX203-3 Beidou Navigation Module is designed based on the OTrack-128A satellite navigation baseband chip, which can receive and process satellite signals at BDS B1, BDS B3 (I/Q), GPS L1, and GLONASS F1 frequencies, achieving real-time three-dimensional positioning, speed measurement, and timing of mobile carriers. Support BDS B3 frequency point long code direct acquisition and positioning, and support BDS B3 frequency point anti narrowband interference function. Its characteristics include high positioning accuracy, short start-up time, small size, low power consumption, and reliable performance. It is suitable for high dynamic carrier navigation and positioning such as handheld devices, vehicles, aircraft, and ships.
a) Equipped with positioning mode switching function, supporting BDS B1, BDS B3 (I/Q), GPS L1, GLONASS F1 single frequency point, dual frequency point, and B1/L1/F1 triple frequency point combination positioning mode;
b) Can detect and eliminate narrowband, burst, deceptive, and other types of interference within the B3 frequency band;
c) Equipped with filling function for PRM and IC modules, supporting self destruction of PRM and IC modules;
d) Capable of receiving RTCM data to achieve pseudorange differential positioning function;
e) Capable of outputting observation data such as satellite pseudorange, Doppler, carrier phase, carrier to noise ratio, etc;
f) Equipped with ephemeris, almanac, time and position injection, and implementing hot start function;
g) Support the "Beidou-2 User Machine Data Interface" (version 2.1).
