Advanced Navigation is pleased to introduce Motus 2, the second generation of their ultra-high performance MEMS Inertial Measurement Unit (IMU).

Motus 2 pushes the performance boundaries of MEMS (micro-electromechanical systems)  gyroscope technology to offer performance greater than many FOG (fibre optic gyroscope) systems in a tiny form factor, ideal for unmanned systems.

Advanced Navigation’s Director of R&D, Nathan Wilson, said “We are very excited to unveil our next generation of MEMS sensor technology with greatly improved gyroscope performance, exceeding many Fiber Optic Gyroscope (FOG) systems. We have been able to reduce bias instability from 0.4 °/hr to 0.2 °/hr and initial bias from 10 °/hr to 3 °/hr. Accelerometer performance is also improved, with initial bias decreased by more than half from < 1 mg to < 0.45 mg. We are able to deliver this solution at an ultra-competitive price point with a SWaP-C (size, weight, power and cost) as low as one-tenth that of equivalent performance FOG systems.”

Motus’ inertial sensors are put through an extensive calibration process that results in consistently accurate data over a temperature range of -40°C to 85°C.

The new Motus is available in an OEM version or enclosed in a rugged aluminium housing, waterproof to IP67 standard, making it highly suited to harsh conditions.

By adding an optional inertial navigation system (INS) license and a GNSS receiver, customers can build a flexible GNSS/INS solution to meet their specific requirements.
