The control problem with consideration of the Schuler period is a special operation mode of the INS-2000 platform inertial navigation system. This mode is used to check the consistency between the calibration parameters of INS sensors and their actual values. Some error equations of INS-2000 are proposed for this mode. Feasible estimation algorithms for INS instrumental errors are tested on model data.

Key words: inertial navigation system (INS), calibration, error equations, estimation.
