Reliable Positioning

The multi-frequency and it’s capability to track all the current constellations enables it receive much more GNSS signals, making RTK accuracy improve a lot.

Automotive Grade

K802 adheres to strict qualification tests for medium and small size applications that requires automotive durability. The K802 has been certified by AEC-Q104 . The K802 takes full advantage of Quantum RTK algorithm from ComNav to deliver reliable and accurate position data in challenge environments.

GNSS+INS Positioning

Combining GNSS positioning technology with inertial navigation system, K802 can offer continuous high quality positioning solution when GNSS signal is not available. It can keep centimeter level accuracy within 3s after losing GNSS signal.
