高精度增强定位连续运行参考服务系统技术研究

摘要

随着我国北斗产品快速发展，多样化的北斗导航定位设备层出不穷，对其定位精度和可靠性的计量检测需求迫在眉睫。传统定位检测主要依靠长时间静态观测，但通过与已知坐标点的比对获得的粗略检测精度指标不能满足动态实时定位检测需求。为此，南京市计量监督检测院建立了一套兼容 BD、GPS、GLONASS 3系统的高精度增强定位连续运行参考服务系统(NJJL-CORS)，为各导航终端提供了稳定可靠的差分数据，实现了实时厘米级的定位精度，为动态计量检测提供了技术平台。%By rapid development of China's beidou products,diversification of beidou navigation positioning equipment have been emerged in endlessly,and the demand of positioning accuracy as well as reliability of measurement test has been also proposed imminently.Mainly rely on static observation for a long period of time,traditional positioning detection could not meet the requirement for dynamic real-time positioning.For the purposes of provide a stable and reliable data for each navigation terminal,accomplish real-time and centimeter level position,and provide a technology platform for the dynamic measurement test,the establishment of enhanced position location continuous operation reference service system(NJJL-CORS) has been built with three systems which were BD,GPS as well as GLONASS by Nanjing institute of measurement and testing technology.
