Zubax GNSS 2

Zubax GNSS 2 is a multipurpose high-performance positioning module interfaced via CAN bus, USB, and UART. It includes a state-of-the-art multi-system GPS/GLONASS receiver, a high-precision barometric altimeter, and a 3-axis compass with thermal compensation. Zubax GNSS 2 supports variety of standard protocols, which ensures compatibility with most of existing software and hardware: UAVCAN (over CAN bus), NMEA 0183 (over USB and UART), and u-Blox M8 protocol.

Zubax GNSS 2 is an open source product - its firmware sources and 3D printable models are freely available from our Github profile page.
