Spatial is a ruggedized miniature GPS-aided combined INS/AHRS, using high-performance MEMS inertial sensors and an advanced multi-frequency RTK GNSS receiver to deliver high-accuracy and reliable position, velocity, acceleration and orientation data.

With a low SWaP footprint and AI-powered sensor fusion capabilities, the state-of-the-art sensor is ideal for marine surveying, USV navigation, and ship motion monitoring. Spatial also features a unique battery backup system that allows the sensor to hot start inertial navigation from its last position in 500 milliseconds and obtain a GNSS fix in approximately 3 seconds.
