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 Standardization of Surveying and Mapping, Ministry of Natural Resources, National Basic Geographic Information Center, Chinese Academy of Surveying and Mapping, Mountain The third geodetic survey team of the Eastern Provincial Institute of Land Surveying and Mapping, Wuhan University and the Ministry of Natural Resources: The main drafters of this standard: Duan Yihong, Zhang Kun, Zhang Peng, Zhang Haiping, Zhao Xin, Gao Shimin, Yin Xiaoqing, Wang Huanping, Wang Xiaohua, Xu Yantian, Wen Hanjiang, Li Lin, Wang Yongshang, Zhang Xi: Terminology of Satellite Navigation and Positioning Base Station

1 Scope

China's national terminology for GNSS reference stations. It covers the general basis, the construction management, the operation and maintenance, and the product services, closing with an index. A reference station is a deceptively simple installation - an antenna on a stable mount, a receiver, a communications link - whose value rests entirely on things that are hard to describe casually: how precisely its position is known, in what reference frame and at what epoch, how stable its monument is against ground movement, how its antenna phase centre is calibrated, and what it does when it loses power or connection. Those are the terms this vocabulary fixes. The structure of the document is telling: it covers not only the technical objects but the management of building, running and serving from a station, because a reference network is an operational service rather than a set of instruments, and most of what goes wrong with one is operational.

This standard specifies the commonly used terms and definitions of satellite navigation and positioning reference stations: This standard applies to the construction, management and application of satellite navigation and positioning reference stations, and can be used for the formulation of related standards and technical documents:

2 General basis
