GPS/GLONASS/BeidDou tri-system board


The UB351/352 board by Unicore Communications.

The UB351/352 GPS/GLONASS/BDS tri-system penta-frequency OEM boards are based on Unicore’s mature multi-GNSS system on chip (SoC). UB351/352 both use a low-power consumption design, support multipath mitigation and offer millimeter-level carrier-phase observations with centimeter-level RTK positioning accuracy.

Instant RTK and high-precision heading advanced technologies are particularly appropriate for applications requiring high-precision positioning, navigation and heading. UB351/352 have been used in several applications in overseas projects, and can be integrated into unmanned aircraft vehicles (UAV) and in precision agriculture.
