As one of Global Navigation Satellite Systems (GNSS) RTK solutions providers, Tersus GNSS brought the latest product release named Precis-BX316, a dual antenna and frequency RTK board and integrated GNSS solutions for UAVs, Precision Agriculture, Surveying, Navigation and Construction Engineering to participate in the grand event.
Extremely affordable but centimeter-level navigation and positioning accuracy GPS/BDS/Glonass RTK boards from Tersus   Application of Low Cost GPS/BDS Receiver in UAV Precise Navigation and Positioning

As the annual event of satellite navigation, the theme of this conference was “Smart Sensing, Smart Perception” and a series of discussions were organized. In the BeiDou/GNSS Navigation Application session, our engineering expert gave a keynote speech in terms of Application of Low Cost GPS/BDS Receiver in UAV Precise Navigation and Positioning.

Precis-BX316, dual frequency and antenna RTK board with heading, onboard SD card for raw data logging, camera shuttle synchronization

The pilot version of Precis-BX316 RTK board was showed during the conference. Precis-BX316 supports GPS L1L2/BDS B1B2/GLONASS G1G2 and with GPS L1L2 heading mode. It supports up to 20Hz RTK solution output and onboard SD card for raw data logging, which is key for post process and data analysis. Camera shuttle synchronization feature for aerial mapping applications is added as well.

Precis-BX316 supports heading with dual antenna input, which provides accurate yaw and pitch angle of moving platform. The official launch of Precis-BX316 is in Q4 this year and datasheet is ready.
