Brief description: ZK-351 satellite navigation receiver is a GPS L1/L2, BDS B1/B2 dual system four-band high dynamic solution engine, up to centimeter-level positioning accuracy, support GPS/BDS single system independent positioning and GPS+BDS multi-system joint positioning, hardware size, interface, data command and imported board compatible.
The dual-star solution engine that is better than the imported board truly realizes the dual-star calculation of GPS+BDS, and adapts to a harsher and longer-distance positioning environment.
【Product Technical Characteristics】
1. The dual-star solution engine is better than that of the imported board, and the dual-star solution of GPS+BDS is truly realized, and it adapts to a harsher and longer-distance positioning environment;
2. Support GPS/BDS single system independent positioning and GPS+BDS multi-system joint positioning;
3. It is compatible with the physical size, electrical interface and command message of the imported board, and can completely replace the imported board;
4. Fast RTK, which can be installed in the measurement GNSS receiver or handheld GIS collector;
