K827 GNSS Board

K827 is comnav’s best-in-class K8 series board. It is a multi-frequency GNSS receiver featuring reliable positioning performance with two independent RTK engine on one board. It can offer centimeter positioning accuracy in harsh environment.

Features

Full-constellation multi-frequency
support GPS, BDS-2, BDS-3, GLONASS, Galileo, IRNSS, QZSS and SBAS
Unique Dual-engine RTK technology
Support INS+GNSS navigation
Support L-Band
Support CAN protocol
50Hz data output
1.8W power consumption

Dual-engine RTK Technology

Observations from primary antenna and secondary antenna are transferred to two processors where RTK are computed independently, so the robustness of system is improved.

Full-constellation & Multi-frequency

K827 can track all the current and planned GNSS constellations, including GPS, BDS-2, BDS-3, GLONASS, Galileo, IRNSS, QZSS and SBAS.

On Board IMU

K827 combines GNSS and IMU to deliver precise positioning in challenging environment. It can keep centimeter-level positioning in 3s and meter-level in 10s during lock-lose.

Strong Compatibility

K827 is compatible with mainstream GNSS boards from physical to data format, ensuring a seamlessly replacement for customers who use boards on worldwide standard 20pins to 28pins.
