An approach to estimating sensor pointing acuruacy is proposed where only the angle-measurement channel is used in the spacecraft information and measurement system. The pointing system utilizes the combined control mode with disturbance compensation. Errors of the filters which evaluate the angular attitude of the target in the body axis coordinate system, discrepancies in the implementation of the combined control mode, and errors of the baseline coordinate system are assumed to be prescribed. The signal hysteresis is also considered.
