SDI multifrequency GNSS Board tracking GPS,BDS,GLONASS

 SDI-204 GNSS Board is developed by our company based on high-performance FPGA.  It tracks signals of BDS B3, GPS L1, and GLONASS L1,  as well as has the ability to  achieve the single-frequency positioning of BDS, GPS,GLONASS  and multi-system compatible positioning. It’s low power consumption and small dimension make it suitable to be embedded. This product is a military miniaturization board with high performance, equipped with functional interface of BDS military code（includes PRM, RTC, encryption chip. At the same time it has abilities of capturing ,tracking military code of BDS and decrypting cable and positioning.

Applications

SDI-204GNSS Board is mainly specialized in the fields of aviation, special vehicle, shipboard system, high-accuracy measurement, etc. Especially it is fit for the carrier who have the need of overload, velocity and environmental adaption.
