Motus

Motus is an ultra-high accuracy MEMS IMU that combines low SWaP-C (Size, Weight, Power, and Cost) and FOG-like performance.

Roll & Pitch

0.05 °


Heading (Magnetic)

0.8 °


Bias Instability

0.2 °/hr


Update Rate

1000 Hz

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.
