Dynamic Calibration Method of Leading information in Integrated Following Equipment

Azimuth of flying object must be produced by position gyroscope instead of encoder when electro-optical countermeasure system is searching and tracing objects on a moving truck.Because of temperature drift and cumulative error of gyroscope fixed on searching axis,flying object cannot be discovered by optical equipment for tracing.The temperature drift and cumulative error of position gyroscope are very hard to be corrected,because they are non-linear with time and temperature.An indirect method to correct the guiding information is presented to solve the problem.
