摘要

摘要网络实时运动学测量(NRTK)是目前大地测量中最常用的测量方法。在大多数国家,都有连续运行参考站(CORS)网络,它们构成了陆地基础设施的核心,可以进行NRTK测量。在包括波兰在内的许多国家,多个CORS网络并行和独立运作。本文介绍了波兰CORS网络的特点。对在波兰运行的5个CORS网络(ASG-EUPOS、NadowskiNET、SmartNet、TPINETpro、VRSNet.pl)进行了为期数天的NRTK和实时动态(RTK)测试,并对测试结果进行了比较分析。测试测量中使用了VRS、FKP、MAC和POJ流。主要研究了当NRTK和RTK测量与不同的CORS网络捆绑在一起对同一点进行测量时,发生系统误差的可能性。对比分析各坐标下NRTK和RTK测量结果的准确度和精密度得出结论。

Analysis of differences in accuracy of positioning tied to various CORS networks in Poland: Case study
Abstract Network Real Time Kinematic (NRTK) measurements are currently the most popular surveying method in geodesy. In most countries, there are networks of Continuously Operating Reference Stations (CORS), which form the core of the terrestrial infrastructure that allows for NRTK measurements. In many countries, including Poland, several CORS networks operate in parallel and independently. The paper presents the characteristics of the CORS network in Poland. The results of several day NRTK and Real Time Kinematic (RTK) test measurements performed tied to five CORS networks operating in Poland: ASG-EUPOS, NadowskiNET, SmartNet, TPINETpro, VRSNet.pl, were subjected to a comparative analysis. VRS, FKP, MAC and POJ streams were used in the test measurements. The research mainly concerned the possibility of the occurrence of systematic errors when NRTK and RTK measurements were tied to different CORS networks for the survey of the same points. Conclusions from the comparative analysis of the accuracy and precision of the NRTK and RTK measurement results for each coordinate were also included.
