Tersus Precis-BX316 GNSS boardTersus GNSS, a provider of real-time high-precision GNSS positioning solutions for unmanned systems, has announced that the company’s newest GNSS RTK board is now available for pre-order.

The Precis-BX316 board, designed for precision position and heading applications, offers real-time, cost-efficient centimeter-level positioning capability. It supports delivering multi-constellation RTK baselines between the two connected antennas and to a remote base station.

Featuring flexible interfaces for a variety of applications, the Precis-BX316 can be integrated via a special connector with other host devices such as UAV autopilots, or used as an independent positioning system. The board supports multi-GNSS RTK positioning, which improves continuity and reliability.

Features of the Precis-BX316:

  • Supports three constellations, six frequencies (GPS L1L2, BDS B1B2, GLONASS G1G2, as well as GPS L1L2 heading mode)
  • Supports 192 GNSS channels
  • Rapid RTK integer ambiguity resolution
  • Instant heading achieved by dual antenna single board
  • Up to 20 Hz position/velocity/time solutions
  • High integration SoC solution
  • Easily integrated to Pixhawk and other autopilots
  • Supports camera shutter synchronization
  • Two serial ports with TTL level
  • External antenna input through SMA connector
  • Data output: NMEA-0183
  • Correction: RTCM 2.x/3.x and CMR
  • Supports logging of raw observation data
  • Compact design and low power consumption
