| Abstract: | In this paper,the position increment algorithm for the position updating of strapdown inertial navigation system is derived and the navigation frame of strapdown inertial navigation systme is the geographic frame.The multi-sample-two-sample,three-sample and four-sample-scrolling compensation algorithms and position rotation compensation algorithms are presented by means of the curve fitting.Simulation results show that the value of the scrolling compensation and position rotation compensation could be computed efficiently by two-sample,three-sample and four-sample scrolling compenation algorithms and position rotation compensation algorithms,and the precision of two-sample,three-sample and four-sample scrolling compensation algorithms and position rotation compensation algorithms increases one by one. |
