Silicon Sensing currently produces three types of multi-axis inertial module. Orion™ – a single-axis gyro and dual-axis accelerometer MEMS combi-sensor chip, DMU10 – a 6-DOF MEMS inertial sensor module and, due for release in the summer, the new DMU30 which is the first of a family of High Performance IMUs (HPIMUs)
