| 摘 要： | GALILEO是新一代的全球卫星定位系统。文章根据GALILEO系统的特点，有针对性地研究了GALILEO／捷联惯导(SINS)伪距组合导航模式。分析并建立了GALILEO的误差方程，并以此为基础，给出了GALILEO／SINS伪距组合导航系统的误差模型和相应的卡尔曼滤波方程。为了有效验证设计的组合导航系统的有效性，在仿真过程中采用了协方差分析法，对组合导航系统性能进行了仿真研究。仿真结果表明GALILEO／SINS伪距组合导航系统能够有效的提高导航精度，随着GALILEO的不断完善，该系统将具有很大的应用前景。

| Abstract: | According to the feature of GALILEO system, this paper focuses on the GALILEO/Strapdown Inertial Navigation System (SINS)pseudo range integrated navigation mode. This paper analyzes and builds GALILEO error equation, and the error mode and Kalman Filter equation of GALILEO/SINS pseudo range integrated navigation system is given. In order to verify the validity of the integrated navigation system designed, the covariance analysis method is used in virtual simulation to study the performance of the integrated navigation system. The results of virtual simulation show that the GALILEO/SINS pseudo range integrated navigation system can increase accuracy validity. Along with the improvement of GALILEO, this system will have a bright application prospect. |
