说明：  本书主要讨论捷联惯导系统算法方面的有关问题，包括姿态算法基本理论、捷联惯导更新算法与误差分析、组合导航卡尔曼滤波原理、捷联惯导系统的初始对准技术、组合导航系统建模以及算法仿真等内容。希望读者参阅之后能够对捷联惯导算法有个系统而深入的理解，并能快速而有效地将基本算法应用于解决实际问题。
(This book mainly discusses the algorithms of sins, including the basic attitude algorithm theory, the sins update algorithm and error analysis, the integrated navigation Calman filter principle, the initial alignment technology of sins, the modeling of integrated navigation system and the algorithm simulation. It is hoped that the reader can have a systematic and thorough understanding of the sins algorithm and can quickly and effectively apply the basic algorithm to the practical problems.)
