We present a method for in-flight calibration of a strapdown inertial navigation system (SINS) for small information satellites. For a satellite SINS, the requirement for the accuracy of attitude determination with small financial expenditures on practical implementation is about 0.05 deg. In this situation, we have applied the variant for the SINS correction based on the signals from a Sun sensor with a set of optical heads and a magnetic sensor. In the paper we consider the problem of the SINS in-flight calibration with such correction at a long-term forecast of the orbital motion of a small information satellite.
