摘　　要：在现有网络RTK技术的基础上,提出了所谓的增强参考站网络的RTK方法,并发展成了具有自主知识产权的高精度网络RTK定位服务系统软件(ARSNET)。实际应用结果表明,增强参考站网络RTK的精度在水平方向上优于±2cm,垂直方向优于4cm,该方法可以有效地提高网络RTK定位的可靠性与性能。An augmentation reference station network RTK positioning software （ARSNet） package has been developed and tested at Southwest Jiaotong University （SWJTU） to provide high-precision RTK positioning service. This software system is currently in operation on Sichuan integrated GPS reference station network in Sichuan, China. Data processing strategies for the ARSNet system, including real time data checking, integer ambiguity parallel filtering with a sidereal filtering to mitigate multi path as well as tropospheric delay modeling were presented and tested. It shows that the RTK positioning accuracy is better than 2 cm in the horizontal direction and 4 cm in the vertical direction within the area of network coverage.
