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.
