Certus

Certus is a dual antenna GNSS/INS that provides accurate position, velocity, acceleration, and orientation under the most demanding conditions.

Roll & Pitch

0.1 °


Heading (GNSS)

0.1 °


Bias Instability

3 °/hr


Position Accuracy

10 mm

Certus combines temperature calibrated accelerometers, gyroscopes, magnetometers, and a pressure sensor with a dual antenna GNSS receiver. These are coupled in an AI-based fusion algorithm to deliver accurate and reliable navigation data. It features low SWaP-C (Size, Weight, Power, and Cost), internal data logging, and multiple communication interfaces for easy integration. Certus is available in both OEM and rugged packages and comes standard with license-free 1 cm RTK position accuracy. Certus Dual Antenna GNSS/INS is compatible with our post-processing kinematic (PPK) software Kinematica.
