Paper Abstract

Transfer alignment(TA) filter is used to estimate the relative attitude errors between a slave inertial navigation system(SINS) and a master inertial navigation system(MINS). Hot studies have been done on match methods of rapid TA in recent years. In practice, in addition to system models, the maneuver plans and filter parameters are also very important to TA process. Without the assistant of appropriate maneuver plans and filter parameters, TA models can not reach excellent filtering performance. Therefore, influences of maneuver plans and filter parameters on TA filter and consistent configuration of them are studied in this paper. Based on a 9-state TA match model, maneuver intensity, maneuver durative time, state predicting covariance matrix P0, state noise matrix Q, observing noise matrix R and filter updating rate as well as their consistent configuration are analyzed respectively. Then, the suggestion of consistent configuration of maneuver plans and filter parameters on TA filter is put forward. Simulation shows that under guidance of the suggestion, TA filter reaches an accuracy of less than 2.5' in less than six seconds.
