Abstract: A software correction method is proposed to reduce the tracking position error caused by the gyro temperature excursion in inertial stabilization systems with position loop. The theoretical foundation of the software correction method and the implementation process of the software correction are presented. The verification experiment for the correction method was carried out. The experiment result shows that the correction program can completely correct the excursion in the case of no vibration, and can still correct the excursion in the case of vibration, but with a code error of 1～2.
