K708 GNSS OEM Board
 
 

The GNSS tracking engine of K708 OEM Board with 496 channels is capable of tracking all the working constellations, which is also reserved for future launched constellations. Compared with K5 series OEM Boards, the K708 adopts the ASIC chip that improves the data quality and reduces the power consumption. In addition, K708 is designed with strong compatibility and built-in functions, including high accurate PVT output, long baseline RTK and reserved webserver service. K708 OEM Board is ideal choice for CORS, Deformation monitoring system and related high-accuracy GNSS positioning applications.
