捷联惯导和GPS组合导航程序，包含初始对准和滤波算法-SINS and GPS navigation program, including the initial alignment and filtering algorithms

四元数法捷联惯导解算算法的matlab程序组合包-Quaternion Solution SINS algorithm matlab program Packs

程序用仿真的方法编制了捷联惯导系统的姿态和航向角解算算法，适合学习算法用。-it is a good programme for them who is studying the algorithm of strapdown inertial navigation.

该程序基于MATLAB平台编写，实现了GPS/INS基于位置松组合的卡拉曼滤波算法，分为两部分，GPS_INS.m为组合算法主文件，输入捷联惯导平台实测数据，设置各量测噪声参数，在调用卡尔曼滤波函数进行数据融合校正，最后实现绘图功能；kalman_GPS_INS.m 为卡拉曼滤波程序，输入量测误差以及各噪声参数可得位置和速度估计值。(The program is based on MATLAB platform, and realizes the Kalman filtering algori
