An algorithm for the bench-test 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 calibration problem in the form of a standard estimation problem is proposed. This method exploits 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 performance of the parameters of an inertial sensor unit. The maximum achievable accuracy for the parameters of the unit is determined.

Key words: strapdown inertial navigation systems, calibration, Kalman filter.
