摘要
Abstract
In the positioning calculation of rotation vector applied in slrapdown inertial navigation system , in order to improve the accuracy of coning error compensation, a general algorithm N sample with M recurrent updating period is provided. The principle of duality between coning and sculling was used to provide the sculling general compensation algorithm. The coefficients of this algorithm can be acquired by a simple matrix computation rather than deduce work. This algorithm can improve the error compensation accuracy without increasing the number of sample through theory analysis and simulative results.关键词
