省级GNSS基准站普查方法探索与实践

Research on Census Method of Provincial Level GNSS Reference Station

近年来,受城市周边建设发展导致的基准站环境变化搬迁、设备使用年限增长和恶劣天气影响,各省GNSS基准站信息发生很大变化。随着我国北斗卫星导航系统(BDS)的发展,需要全面了解基准站信息状况,及时更新维护现代测绘基准体系。以HBCORS为例,探索了GNSS基准站普查的目的、内容和方法,提出了普查的技术流程、关键问题和解决方法,并在湖北省GNSS基准站普查工作中进行了实践。结果表明,该方法可在其他地区推广,具有实践意义。

In recent years,due to the environmental changes and relocation of reference stations caused by the construction and development around cities,the increase of equipment service life and the influence of bad weather,the information of GNSS reference stations in various prov-inces has changed greatly.With the development of BDS in China,it is necessary to fully understand the information status of reference stations and timely update and maintain the modern surveying and mapping benchmark system.Taking HBCORS for example,we explored the purpose,content and method of GNSS reference station census,put forward the technical process,key problems and solutions of census,and put it into practice in the GNSS reference station census in Hubei Province.The result shows that this method can be promoted in other areas and has practi-cal significance.
