On the Optimal Measurement Time in North-Finding Procedures using Maytagging

This article deals with gyro-based North-Finding by using the Maytagging approach. One proposes an analysis of the Maytagging effect on the variance of the estimated azimuth, in function of the gyro disturbances (bias and noise). It is shown that it is preferable to impose a reduced time duration of the Maytagging sequences, and to multiply the number of these sequences.
