K726 GNSS OEM Board

The K726 is designed with dual-antenna input that delivers high-precision positioning and heading for various unmanned systems.

The K726 is a single GNSS board that delivers robust heading and positioning. With dual-antenna input design, observations from both antennas are transferred to the processor where multi-constellation RTK are computed. It is able to deliver centimetre-accuracy positioning and high-precision heading both in static and dynamic environments.
