Motus is a miniature IMU (inertial measurement unit) that utilizes some of the most accurate MEMS accelerometers and gyroscopes on the market, providing inertial performance that rivals even some FOG IMUs. The unit can be upgraded to full AHRS or INS capability via an easily-applied software license upgrade.

With a volume of just over 1 cubic inch and a weight of only 26 grams, Motus is ideal for SWaP-conscious marine survey platforms. It is available as an OEM board for system integrators, or in a ruggedized housing.
