Аннотация
Errors of a strapdown inertial navigation system (INS) based on navigation grade fiber-optic gyros (FOG) are studied, with the INS measurement unit performing modulation rotation about the axis orthogonal to the vehicle deck. The main focus is made on the problem of reducing the time of gyro in-run drifts calibration, using the GNSS data when the INS is turned on. In addition to velocity and position measurements taken by the GNSS, phase measurements from antennas spaced on a certain baseline are included.
