“…Furthermore, these aircraft generally require two inertial units, one for the control of the vehicle and the other for navigation data. It is only recently that fighter aircraft such as the Eurofighter have implemented a single inertial unit for the dual purpose of control and navigation (Ebner and Mark 1978). In all cases, however, the sensors employed, and in particular the gyros, are of high performance.…”

This paper discusses the development of a low-cost, redundant, strapdown inertial measurement unit (IMU). The unit comprises four ceramic vibrating structure gyroscopes and four QLC 400 accelerometers configured on a truncated tetrahedron design. This design allows for the optimal configuration of the eight sensors, which in turn provides for a theoretical 33% increase in information. The redundant sensor configuration also allows for fault detection, which is required for many autonomous applications. This initiative is a precursor for future developments with more sensors to provide fault isolation. The paper will also present a navigation system implementing the redundant IMU with the global positioning system. Results are provided of this navigation system being implemented in an unmanned air vehicle.

“…The method is simple and popular. However, parity space methods have problems with singularities caused by the relationship between the configuration of the sensors and the motion of the vehicle (Ebner and Mark 1978). Faults cannot be detected within these singularities.…”
