High Accuracy and Fast Alignment Method for Single-axial Rotation SINS
摘要
Abstract
It needs prolonging the coarse alignment time to improve the accuracy of the coarse alignment under the rocking condition.Otherwise,it can’t control the azimuth error in the small range,then the fine alignment will converge slowly.To solve this problem,a high accuracy and fast alignment method which uses reverse navigation technology is put forward for rotary SINS.This method prolongs the coarse alignment time mostly,then saves the data of SINS to carry on fine alignment.It use the data of alignmet sufficiently and improve the alignment accuracy mostly in certain alignment time.The result of test indicated this method is not only reduce amount of calculation,but also simplify the algorithm ,it can also achieve fast alignment of rotary SINS and can acquire high accuracy.All this characteristics prove that the method is valuable in engineering application.关键词
