摘要
介绍了影响网络RTK精度的相关因素,通过实验分析与研究得出,影响网络RTK精度的主要因素有:网络RTK定位点的有效卫星数、GDOP值、流动站与参考站间的距离、初始化时间、周围环境等。最后,结合理论和实验指出了网络RTK应用时应注意的问题,为CORS系统的实际应用提供参考。
This text introduces the ingredients affecting the precision of the network-RTK. By test, the text analyzes and researches the positioning precision affection which are brought by the effective GPS satellite number, GDOP, distance interval between the Continuous Operation Reference Stations, OTF, environment around etc. Integrating the test with the theory of the Network-RTK, It gained the advice which is noticed by the actual application of the Network-RTK and offers the technique reference and task guidance for the application of the CORS System.
