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.   a formal model for integrity protection based on dte technique 期刊论文  OAI收割 Science in China Series F: Information Sciences, 2006, 卷号: 49, 期号: 5, 页码: 545-565 Qingguang Ji; Sihan Qing; He Yeping   |  收藏  |  浏览/下载：28/0  |  提交时间：2010/08/23 formal model  integrity policy  information flow  domain  type  ENFORCEMENT  DOMAIN   a practical alternative to domain and type enforcement integrity formal models 会议论文  OAI收割 2nd SKLOIS Conference on Information Security and Cryptology, Beijing, PEOPLES R CHINA, NOV 29-DEC Tang Liuying; Qing Sihan   |  收藏  |  浏览/下载：30/0  |  提交时间：2011/07/28 security label  security goal  integrity  information flow  formal model   Optimized design model for sediment-trapped dam by GIS techniques 期刊论文  OAI收割 SCIENCE IN CHINA SERIES E-ENGINEERING & MATERIALS SCIENCE, 2003, 卷号: 46, 期号: S, 页码: 175-187 作者:  Li, FB;  Tu, JJ;  Ku, KH 收藏  |  浏览/下载：22/0  |  提交时间：2010/11/30 debris flow  sediment-trapped dam  geographical information system  optimized design  model
