Motus Ultra-high Accuracy MEMS IMU

Motus features some of the highest accuracy MEMS accelerometers and gyroscopes combined with a sophisticated fusion algorithm to offer FOG-like performance. Its market-leading SWaP-C (Size, Weight, Power, and Cost) make it ideal for autonomous system applications. Motus is available in both OEM and rugged packages.



Motus IMU | Advanced Navigation

Ultra-High Accuracy MEMS

Motus features some of the highest accuracy MEMS accelerometers and gyroscopes currently available. Motus’s inertial performance exceeds some FOG IMUs and is up to 100x smaller and 10x cheaper. Motus is put through Advanced Navigation’s intensive calibration process to provide consistently accurate data over an extended temperature range of -40°C to 85°C.
Miniature Package

Miniature Package

Never before has such high inertial performance been available in such a small package. Motus consumes just over 1 cubic inch in volume and weighs only 26 grams. This makes it ideal for weight and size sensitive applications. Motus is available in an OEM package suitable for integration into larger products or an enclosed package for external and standalone use.

Signal Processing

Advanced Signal Processing

Motus samples its sensors synchronously at 1000Hz through six individual 24-bit differential ADCs which minimises noise as well as providing optimal thermal calibration and performance characteristics. 14 seperate heavily filtered regulated power supplies ensure that each sensor and ADC is operating off the cleanest possible power supply.

Trusted Reliability


Motus has been designed from the ground up for mission critical control applications where reliability is very important. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in mind. The hardware is designed and manufactured to mil standards.

High Sampling Rate

High Update Rate

Motus outputs temperature calibrated sensor data at 1000Hz as well as filtered attitude at the same rate. This allows for control of dynamically unstable platforms.
