| 摘 要： | 采用最小二乘协方差方法分别对Galileo系统的定位误差和中国区域导航增强系统的定位误差的计算进行定义,并通过matlab编程仿真比较得出:区域增强导航系统的定位误差只有Galileo系统定位误差的三分之一。表明,如果能建立区域增强导航系统将在较大程度上提高中国区域的导航能力。

| Abstract: | The calculation of position errors in the Galileo system and the regional augmentation navigation system with least-squares covariance analysis is presented in this paper.According to the simulation results,the the regional augmentation navigation system is one third in error for Galileo position.Therefore,if the regional augmentation navigation system can be founded,our navigation capacity will be greatly improved. |
