IMUs and 3D compasses

Inertial units, IMUs and electronic compasses are geolocation and navigation instruments equipped with inertial sensors (inclinometer, acceleromer, gyroscope). They provide two advantages:

• allow very precise geolocation and navigation in the absence of a GPS signal. Example: tunnel, drilling, at sea, in flight, etc ...
• Allow more precise position tracking than what GPS offers in tight spaces.

Applications: robotics, autonomous vehicle, construction machinery, agriculture.
