| 摘 要： | 卫星导航定位基准站网不仅是提供国家、区域、全球高精度时空基准的重要基础设施,也是导航与位置服务、精密卫星定轨、地质灾害监测等工程和科学研究的重要支撑。当前,随着基准站网规模的不断增加、观测数据的不断积累以及我国北斗系统的逐步建成,无论在卫星导航定位数据处理理论还是应用方面,基准站网的发展面临着不少机遇与挑战。本文首先给出了基准站网的定义和类别,并描述了功能与意义;然后分析了其发展的历史与现状;最后从基准站网的建立、数据处理理论与方法、应用三方面讨论了所面临的机遇与挑战,并给出了一些建议和想法。

| Abstract: | GNSS(Global Navigation Satellite System) reference station network is not only an important infrastructure to provide national, regional and global high-precision time and space datum, but also is an important support for navigation and location services, precise satellite orbit determination, geological disaster monitoring and other scientific and technological applications. At present, with the increase of reference station network of continuously operating reference system (CORS) and the rapid establishment of BeiDou, the development of the networks is facing many opportunities and challenges. Firstly, this paper gives the definition and classification of the GNSS reference station network, and describes its function and significance. And then the history and present situation of development of the network are analyzed. Finally, we discuss the challenges and opportunities of the network based on its establishment, data processing theory and method, application. |
