Tersus GNSS has released to the market its new GNSS PPK board, the Precis-BX316R. Precis-BX316R is a GNSS Post-Processing Kinematic (PPK) board for accurate positioning. It supports raw measurement output from two antennas: GPS L1/L2, GLONASS G1/G2 and BDS B1/B2 from primary antenna and GPS L1/L2 from the second. The SD card on board (up to 32G) makes it convenient for users to collect data for post processing. Working with GNSS antennas, it can output stable measurement in challenging conditions, Tersus GNSS said. Integrated with versatile interfaces and connectors, Precis-BX316R aims to facilitate applications such as precision navigation, precision agriculture, surveying and UAV, and enforcing effective GNSS data management.
