The integrated system of "Beidou" Double-star/DR is studied in this paper according to the present state of vehicle navigation in our country. "Beidou" Double-star navigation position system is one regional satellite position system built up by our country  which can provide rapidly not only highly precision position and brevity telegram service. However  when the vehicles go around the tall buildings  high mountain area  wayside trees and in the tunnels  all signal may not be received. If the satellite navigation position system is used only  the precision will be reduced. Therefore  this paper proposes a nonlinear self-adaptive Kalman filter model and its algorithm for a Double-star/DR integrated navigation system in land vehicles  and verifies effectively the algorithm and scheme through the means of simulation. Next  this paper introduces map match approach. The roads are segmented and character information is brought out. Then  proper search rules and map match algorithm are adopted. According to the current vehicle position information that Double-Star/DR system provides  the nearest road can be found in the map database. The vehicle position will be matched and displayed on the road. The result of the experiment shows that the Double-star/DR integrated algorithm and map match can improve reliability and the precision of vehicle navigation system efficiently.   数字海底数据库：海底多源综合数据的集成与管理方法研究 期刊论文 海洋科学进展, 2005, 卷号: 23, 期号: 4, 页码: 504-512 作者:  苏天赟;  刘保华;  翟世奎;  梁瑞才;  郑彦鹏 收藏  |  浏览/下载：6/0  |  提交时间：2019/08/19 数字海底  数据库  空间数据引擎（SDE）  ORACLE数据库管理系统  digital seabed  database  spatial data engine（SDE）  ORACLE database management system   数字海底数据库：海底多源综合数据的集成与管理方法研究 期刊论文 海洋科学进展, 2005, 卷号: 23, 期号: 4, 页码: 504-512 作者:  苏天赟;  刘保华;  翟世奎;  梁瑞才;  郑彦鹏 收藏  |  浏览/下载：2/0  |  提交时间：2019/03/13 数字海底  数据库  空间数据引擎（SDE）  ORACLE数据库管理系统  digital seabed  database  spatial data engine（SDE）  ORACLE database management system   基于计算机控制的TCSC装置数字仿真研究及实验系统软件设计 学位论文 2005, 2005 张丹 收藏  |  浏览/下载：5/0  |  提交时间：2016/02/14 可控串联补偿器  基波阻抗  关系数据表  谐振点  TCSC人机交互系统软件平台  Thyristor Controlled Series Compensators (TCSC)  Basic Frequency Equivalent Impedance  Functional Relationship Database  Resonance Point  Human-machine Interaction System Software Platform   Quantitative study of circadian variations of ambulatory blood pressure in Chinese healthy, hypertensive, and diabetes subjects 期刊论文 Clinical and Experimental Hypertension, 2005, 卷号: 27, 期号: 43134, 页码: 187-194 作者:  Zhao Z.-Y.;  Zhao Z.-Y.;  Wang Y.-Q.;  Yan Z.-H.;  Cui J. 收藏  |  浏览/下载：3/0  |  提交时间：2020/01/03 ABP  Circadian variation  Database system  Parameters of ABP   Power control algorithm for wireless cellular system 期刊论文 Zidonghua Xuebao/Acta Automatica Sinica, 2005, 卷号: 31, 页码: 239-247 作者:  Cai, Min;  Zhang, Huan-Shui;  Wang, Wei 收藏  |  浏览/下载：6/0  |  提交时间：2020/01/02 Distributed database systems  Interference suppression  Parameter estimation  Power control  Stochastic control systems, Distributed algorithm  Interference estimation  Stochastic approximation  Wireless cellular system, Wireless telecommunication systems   Research on data collection and database update of GIS based on GPS technology 会议论文 25th IEEE International Geoscience and Remote Sensing Symposium (IGARSS 2005), Seoul, SOUTH KOREA, 2005-07-25 作者:  Han, M;  Tian, X;  Xu, SG 收藏  |  浏览/下载：2/0  |  提交时间：2020/01/02 Geographical Information System (GIS)  Global Positioning System (GPS)  data collection  database update   对分布式协同设计中多媒体系统的语义的分析表达 会议论文 2005年全国理论计算机科学学术年会 作者:  陈娟 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/31 Semantic analysis  Semantic database  Distributed multimedia system   Quantitative study of circadian ambulatory blood pressure variations of in Chinese healthy, hypertensive, and diabetes subjects 会议论文 5th Japanese Annual Conference on Chronocardiology and Hypertension, 2003 作者:  Zhao, ZY;  Zhao, ZY;  Wang, YQ;  Yan, ZH;  Cui, J 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/31 ABP  database system  circadian variation  parameters of ABP   基于XML/SVG的WebGIS在城网配电自动化系统中的应用 会议论文 第二十二届中国数据库学术会议 作者:  孙涛;  王新军 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/31 XML  SVG  WebGIS  Database system
