Description
The µIMU is based on MEMS technology. It is a complete inertial measuring unit, comprising three MEMS rate gyros, three MEMS accelerometers, the associated electronics and a power supply, all enclosed in a hermetically sealed robust housing.
With its small size, its easy-to-integrate interface and its excellent performance data, the µIMU is the perfect measuring unit for all applications such as attitude-heading reference systems and stabilisation systems, as well as for the stabilisation of cameras, antennas and other instruments on mobile platforms.
