Abstract

The effect of mutual delays in rate sensor (RS) channels on the accuracy of a strapdown inertial navigation system (SINS) has been studied. Two types of SINS motion have been identified, for which the delays of about one microsecond in the RS channels result in significant navigation errors. Sensitivity of navigation errors to the deviations from these motions has been investigated, as well as the effect of delays in the RS channels on real trajectories registered in course of flight tests.
