Spatial (NRND)

Spatial is a miniature GNSS-aided INS that provides accurate position, velocity, acceleration, and orientation under the most demanding conditions.

Roll & Pitch

0.1 °


Heading (GNSS)

0.2 °


Bias Instability

3 °/hr


Position Accuracy

20 mm

Spatial combines temperature calibrated accelerometers, gyroscopes, magnetometers, and a pressure sensor with an advanced GNSS receiver. These are coupled in an AI-based fusion algorithm to deliver the most reliable and accurate navigation data in its class. Spatial is available in both OEM and rugged packages. Spatial is compatible with our post-processing kinematic (PPK) software Kinematica.
