| 摘 要： | 从SINS／GPS（Strapdown Inertial Navigation System／Global Position System）组合系统算法设计的总体方案入手，给出了低动态载体定位或高动态载体短时定位用的一种捷联解算算法，推导了SINS／GPS组合算法采用的惯性测量误差方程，结合某载体运动参数，对几种情况下的SINS／GPS组合定位误差进行了仿真，并对仿真结果进行了比较，为工程应用奠定了基础。

| Abstract: | The scheme of SINS/GPS combination algorithm is put forward firstly. Then, the strapdown algorithm using for positioning in low dynamic vehicle or in short time moving vehicle has been given, and the error equations have been deduced. The positioning error has been simulated under several given conditions, whereafter the results of simulation have been compared. This work has laid the foundation for the engineering application of SINS/GPS combination system. |
