摘要
针对网络RTK技术在各个领域广泛应用的几种关键技术,介绍了当前各种技术的原理,并逐一进行了比较分析。采用误差综合的方法推导VRS的定位模型,提出主辅站采用邻近全网基线解算的技术优势。认为应合理选取建设哪一种网络RTK服务,系统的管理维护和系统兼容性是未来网络RTK研究领域的重点问题。
Network RTK technology is widely used in various field these days, this paper introduces the different theories and compares the key technologies. The combined error theory is adoptd for the VRS orientation model. The advantages about the use of neighbor network baselines in MAC is pointd out in the paper. Besides, the useful advices that which Network RTK technology should be in reason are suggested for the users. Finally, the management and the compatibility should he the key important research topics in the future development.
