A Miniaturised Space Qualified MEMS IMU for Rover Navigation
In Proceedings of the 11th Symposium on Advanced Space Technologies in Robotics and Automation, (ASTRA-11), 12.4.-15.4.2011, Noordwijk, o.A., Apr/2011.
A recent ESA R&D activity, led by ÅAC, including SEA and DFKI, was undertaken to develop a miniaturised MEMS based inertial measurement unit (IMU) for use in rover navigation systems for planetary or lunar exploration missions. It has been part of the Technology Research Program (TRP) at ESTEC allocated in the Automation & Robot Section. The miniaturised IMU study showed the feasibility of such a unit by deriving requirements from the targeted missions, and showing how these can be met. The study was supported by developing, manufacturing and testing a functional breadboard demonstrator and by testing material mock-ups under target environmental conditions. This paper provides a brief introduction into the design options, the miniaturisation using ÅAC proprietary multi wafer packaging „via‟ technology and the results of the environmental tests. Another focus lies on the derivation of the requirements, and the testing of the IMU breadboard prototype.
