By analyzing mathematics model of the first system error  we found that inertia velocity error would cause code loop track error. Consequently  the pseudo range meterage error is interrelated with inertia velocity error  which is complex to calculate. If this relativity is ignored in the state equation and observation equation of this system  it must affect the estimated precision of the kalman filter and maybe the system is unstable. Therefore  the second integrated navigation method is introduced. It adopts information fusion  federal kalman filter and covariance. And consider the above pertinence to analyze the navigation performance of the integration system. Then it gives the flow of federal kalman filter algorithm. By analyzing  the conclusion is that velocity error of integrated navigation system drops from 0.5m/s to below 0.05m/s  and improves the precision and reliability of the navigation system effectively  well continuity and real-time capability. It provides an effective way for data analysis and process of fusion navigation system. 2006 IEEE.   Mountain-based GPS observations of occultation and its inversion theory 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2006, 卷号: 49, 期号: 1, 页码: 22-27 作者:  Hu, X;  Zhang, XX;  Wu, XC;  Xiao, CY;  Zeng, Z 收藏  |  浏览/下载：26/0  |  提交时间：2015/07/17 mountain-based GPS radio occultation observation  atmospheric refractivity  ray bending angle  lower atmosphere  inversion
