Abstract


The paper deals with basics tasks of the design of redundant noncollinear inertial measuring units based on the  technology of micrielectromechanical systems. Analysis of noncollinear configurations of inertial sensors is represented. The approach to the creation of the mathematical model of the inertial sensor is given. The basic problems of redundant information processing are discussed. The problem of optimal orientation of inertial sensors sensitivity axes in noncollinear configurations is studied. The approaches to conversion of redundant measuring information into projections of moving vehicles kinematical parameters are represented. The possibility to use the criterion of maximum a posteriori probability and least-squares method is considered. The ways to solve the above-mentioned problems are proposed. The obtained results can be useful for the  design of inertial measuring units of the wide class
