Product Review | Top Rated

The ZK-HDS GNSS Differential Positioning System is a best solution for precise position and heading. The system consists of two components: the GNSS reference station and the GNSS rover. Both the reference station and the rover are integrated with wireless communication radio. Upon receiving the differential correction data from GNSS reference station, the rover achieved differential positioning and provides high-precision position with centimeter-level accuracy. Additionally, the rover can be connected to two GNSS antennas. Heading derived from dual-antenna GNSS measurements.
