Batch‐Processing of Inertial Measurements for Mitigation of Sculling and Commutation Errors

: A new approach to improve the accuracy of the positioning and velocity outputs of an inertial navigation system is proposed in this paper. This approach implements coordinate transformations and attitude computations by means of batch-processing in the frequency domain. Test results demonstrate that this approach is superior to traditional time-domain processing for reconstructing sculling and coning motions, thereby reducing sculling and commutation errors in the INS output. Application areas where this superior performance is a significant benefit include motion compensation for synthetic aperture radar and airborne light detection and ranging.
