| 摘 要： | 在SINS/GPS组合导航系统中,由于实际所限,无法进行物理试验,一般都采用仿真方法来进行设计和验证.因此在Matlab/Simulink仿真平台中,游移方位系的捷联惯导力学编排进行导航计算,以GPS接收机的伪距为观测量,建立组合导航系统的状态方程和观测方程,在地心地固系内进行Kalman滤波融合,并进行了奇异值可观性分析.系统仿真和可观性分析结果表明:设计的导航系统能够获得满意的精度和可观性.

| Abstract: | During the development of SINS/GPS integrated navigation system,field trial can not be conducted because of real limitations. In general,the simulation is used in the process of integrated navigation system design and validation. In the paper,the wander azimuth mechanization under Matlab/Simulink was used for c SINS (strapdown inertial navigation system ) computation. The pseudo-range output of the GPS receiver was taken as measurement. Then,the state and measurement equations were set and filtering fusion ... |
