RACID's are successfully employed in star tracking and celestial navigation applications where only designated stars within the canopy of space are read and processed for positional vectoring.

RACID已经成功的应用于恒星追踪，天体导航应用，此时，指定的星体可以定位引导的读取和处理。

In this paper, the basic mathematical model was derived by means of two methods, the first is the twostar positioning algorithm in celestial navigation theory and the second is based on the gyro dynamics theory. The results from these two methods are identical and therefore are correct. The latitude is equal to the elevation-angle of the polar gyro. The course is the ideal output from the sensor fitted to the outer gimbal. The longitude is a function of the equator gyro's azimuth and elevation angles.
