Abstract
This article discusses an approach to the construction of inertial orientation and navigation systems using structural redundancy. The structural redundancy of the inertial module is achieved by installing an excessive number of primary information sensors the sensitivity axes of which are non-orthogonal to each other. This approach to building an orientation and navigation system increases its reliability, accuracy and fault tolerance. An example of a technical solution for a small-sized inertial orientation and navigation system with structural redundancy based on a MEMS accelerometer, a MEMS gyroscope and a magnetometer for aviation applications is given. A mathematical model and algorithm for processing the output signals of an orientation and navigation system with structural redundancy are presented. The evaluation of the comparison of the accuracy of orientation and navigation systems with and without structural redundancy was performed.
