Foreword

This standard was drafted in accordance with the rules given in GB/T 1:1-2009: This standard was proposed by the Ministry of Natural Resources of the People's Republic of China: This standard is under the jurisdiction of the National Geographic Information Standardization Technical Committee (SAC/TC230): Drafting organizations of this standard: Institute of Surveying and Mapping Standardization, Ministry of Natural Resources, Zhejiang Surveying and Mapping Quality Supervision and Inspection Station, China Surveying and Mapping Scientific Research Institute, National Basic Geographic Information Center, Fujian Institute of Surveying and Mapping, Wuhan University, Geodetic Data Processing Center of Ministry of Natural Resources, Ministry of Natural Resources Chongqing Institute of Surveying and Mapping: The main drafters of this standard: Guo Yufang, Deng Guoqing, Ge Zhonghua, He Shujing, Huang Gongwen, Ren Fu, Zhang Jing, Chen Ming, Wang Tiejun, Wu Tong, Xu Yantian, Shen Zhongshu, Zhao Lijian, Du Zhongjin, Wen Hanjiang, Xie Xiuping, Zhang Zhiyong, Cheng Yaxuan, Li Rongchun: Satellite navigation and positioning base station network in real time Dynamic Measurement (RTK) Specification

1 Scope

China's national specification for network RTK surveying. Real-time kinematic positioning gives centimetre accuracy in seconds by correcting a rover's satellite observations against a reference station's, and network RTK extends it: instead of one base station whose corrections degrade with distance, a network of permanent stations models the errors across a region and generates a correction tailored to wherever the rover happens to be. That removes the base station from the surveyor's work entirely - the rover connects over the mobile network and works anywhere in the coverage. China has built out this infrastructure more comprehensively than anywhere else. What the specification has to fix is how a survey using it is conducted and checked, because the ease of the method conceals its failure modes: a fixed solution can be wrong, and a surveyor who does not re-initialise and check will not know.

This standard specifies the reference for real-time dynamic survey (RTK) technology implementation of satellite navigation and positioning reference station network for control survey and topographic survey Benchmarks, basic requirements, and technical requirements and methods for field observation, data processing and testing: This standard applies to the real-time dynamic measurement of the satellite navigation and positioning base station network of the corresponding level: Use single base station, multiple base stations Real-time dynamic measurement can refer to this standard:
