The Tersus GNSS Precis-BX306. Tersus GNSS Inc., a GNSS real-time kinematic (RTK) manufacturing company, has launched its new GNSS RTK board, the Precis-BX306. The launch of Precis-BX306 aims at facilitating the applications that need centimeter positioning accuracy and dynamic operation mode, enforcing effective observation data logging and management, and popularizing the adoption of high precision in aerial mapping and drone-related integration. Compared with previous Precis GNSS RTK boards, Precis-BX306 further improves the reliability and continuity of positioning performance in challenging environments. It supports GPS L1/L2, GLONASS G1/G2 and Beidou B1/B2 with 192 tracking channels. The Precis-BX306 can easily integrate into Pixhawk and other autopilots. The event mark and PPS features of the new board provide more possibilities for shutter synchronization.
