The coupling between microsensors and efficient signal processing is essential to achieve demanding specifications for navigation applications. The performances of a silicon micromachined angular rate sensor are outlined showing that the main shortcoming consists of an important offset drift. This error is modelled and used in a correction algorithm based on Kalman filtering. The filter aims at...

The project presented in this paper aims at defining the limits of microsystems through the realisation of a navigation system based on inertial microsensors. The work includes (i) design, fabrication, characterisation of accelerometers and angular rate sensors, (ii) development of techniques for simulation of sensor behaviour, and (iii) design of a sensor data processing system.
