Description
Summary:An algorithm for the bench calibration of strapdown inertial navigation systems is studied. This algorithm was developed at the Moscow Institute of Electromechanics and Automatics. A mathematical model for the calibration process is constructed. A method for representing the original calibration problem in the form of a standard estimation problem is proposed with the aid of a so-called “telescopic” system. On the basis of the original algorithm, a new calibration algorithm is constructed; this new algorithm allows one to improve the estimation accuracy for the parameters of accelerometer and gyroscope units. The maximum attainable estimation accuracy for these parameters is determined.
