The compensation optimal algorithm of angular attitude plays a very important role in the output operation model of the dynamic slant calibrating sensor.The performance of the algorithm determines the accuracy and real-timeness of output.This paper designs an attitude algorithm for the strapdown system taking advantage of the fact that the contributions to the coning compensation by the cross products of the two incremental angles having equal time intervals are the same under the condition of coning movement.If the coning compensation accuracy is the same,the calculation burden of this algorithm will be decreased.A compensation algorithm is also introduced,by which the angular increment in the former coning compensation period reduces the operation time and improves the compensating accuracy.
