摘要
北斗卫星导航系统是中国自行研制的全球卫星导航系统,也是继GPS、GLONASS之后的第三个成熟的卫星导航系统。中国软件评测中心通过实施基于北斗高精度导航定位的智能交通应用示范项目,开发出了由中心服务子系统、全球导航卫星系统(GNSS)基准站子系统、车载终端子系统和人员终端子系统构成的北斗高精度导航定位系统,以及与校车应用场景相配套的路径规划算法和联合定位算法,演示系统在泰国进行了部署与测试,对其电子围栏、实时轨迹、轨迹回放功能进行了验证,并对其车载终端单点定位精度、RTK定位精度、车载终端速度精度、人员终端单点定位精度、人员终端伪距差分精度等关键性能指标开展了测试,测试结果进一步验证了北斗高精度智能交通系统在国内外的应用可行性。
BeiDou navigation system is the self-developed Global Navigation Satellite System of China and the third mature satellite navigation system after GPS and GLONASS.China Software Testing Center developed the BeiDou high precision navigation system by implementing the demonstration of intelligent transportation based on BeiDou Navigation Satellite System project.The system includes central service subsystem,GNSS reference station,vehicle terminal subsystem and personal terminal subsystem,using the path planning algorithm and the joint localization algorithm which match with the school bus demonstration scene.The system was deployed and tested in Thailand,and its electronic fence,real-time track and track playback functions were verified,and the key performance indexes of its vehicle terminal single point positioning accuracy,RTK positioning accuracy,vehicle terminal speed accuracy,personnel terminal single point positioning accuracy,Personnel Terminal pseudo-range differential accuracy were tested.The test results verify the application feasibility of BeiDou high precision system at home and abroad,and promote the application and popularization of Beidou Global System.
