摘要
VRS(虚拟参考站)技术是网络RTK技术的一种,它与传统测量技术和传统RTK技术相比有很多优点。结合上海市徐汇区地籍校正测量的实践,探讨了VRS技术在城市繁华地区进行控制测量的可行性和应注意事项,并对测量数据进行分析。结果表明,利用VRS技术布设控制点不仅精度高、速度快,而且结合全站仪使用可以高效地完成地籍测量工作。
VRS is one of the network RTK technologies ; it has many advantages compared with the traditional survey and RTK technology. Based on the practical survey of correcting cadastre map of Xuhui district in Shanghai city, this paper discusses the feasibility and notices when VRS technology used in city control survey. The paper also gives a brief analysis of measured data. The result indicates the VRS technology has not only high accuracy and fast speed, but also high efficiency when used to carry out the cadastre survey combined with the total station.
