Maglev gyroscope data characteristics based on two positioning methods

摘要：

　　Through the analysis of two-position sampling data based on the maglev gyroscope north seeking theoretical model and the verification of north seeking experiments results via several aspects, it was found that there were systematic deviations between the maglev gyroscope north seeking process and the theoretical model.Its mainly reflected in the deviation of the trend term deviation and constant deviation related to the north seeking erection orientation.They dont impact the stability of north seeking according to our analysis.The constant deviation impact the absolute north seeking accuracy, but it can be offset by data differential.Finally, the author believe that the maglev gyroscope north seeking data characteristics can be used as priori conditions of data filtering and elimination of gross error.It can also be used in the assessing precision of the gyroscope orientation.
