Why Tersus GNSS

How We Ensure Accuracy in Land Surveying

Advanced multi-frequency GNSS technology combined with IMU tilt compensation and PPP correction services. Our equipment reduces operational costs while delivering the accuracy professional surveyors demand.

8mm

RTK Accuracy

Horizontal positioning accuracy in real-time kinematic mode with 1ppm distance factor.

<10s

Initialization

Hot-start RTK fix time gets you measuring within seconds of powering on.

1408

GNSS Channels

Track all available constellations simultaneously for maximum reliability.

60°

Tilt Range

Measure without leveling the pole — IMU-based tilt compensation to 60 degrees.
