网络RTK定位精度影响因子与GNSS数据网络传输研究
|
摘要
本文以自主建设的单参考站系统实验平台为基础,结合北京市CORS系统,采用试验与理论分析相结合的方法,对两个关键问题展开研究：网络RTK系统中定位误差影响因子；GNSS数据网络传输的安全性与稳定性。提出通过确定与区域定位误差相关的空间特征因子,结合有针对性的措施,从而提高已建成的网络RTK系统定位精度的思路。将二维列联表的χ2检验与似然比检验方法应用到影响网络RTK定位精度的因子分析中,给出了进行测点种类与空间特征因子相关性研究的具体分析过程,并论证了该方法的理论意义和实际价值。在全面论述NTRIP协议系统构架、工作原理的基础上,结合数据中心GPSBase数据处理软件与GNSS Internet Radio软件实现了NTRIP协议,成功解决了GNSS数据网络传输中差分时延过长、差分定位不稳定等问题。并将此开发方法应用到GPS穿孔制导原型系统中,通过实际应用验证了本文理论和方法的正确性。
By means of experiment and theory analysis methods, two key issues:the positioning error factors analysis and the network communication protocols of Network RTK system are mainly studied based on the single reference station system experimental platform which was independently established and the research environment of Beijing CORS.This dissertation put forward the opinion that the performance of Network RTK can be promoted by determining the regional spatial characteristics factors which influenced positioning accuracy and adopting the pertinence measures. On the basis of the comprehensive discussion of NTRIP system architecture and working principle, Trimble GPSBase data processing software was combined with GNSS Internet Radio software to implement NTRIP protocol, by which the problems during the GNSS data network transmission process, such as longer differential delay and positioning instability were successfully solved. The GPS drilling guidance prototype system used this proposed method is also presented to verify the correctness of these theories and approaches.
