日本地理空间信息管理局运营着世界上最大的持续运行的全球导航卫星系统参考站网络之一--GeoNet，该网络由日本境内1300多个基于全球导航卫星系统的控制点组成。GeoNet已成为测绘、监测地壳形变和减轻自然灾害的社会基础设施。它还用于精确定位，以指导建筑和农业机械，甚至用于天气预报。在这里，我们回顾了它的历史和前景，重点介绍了它在减灾中的应用。由于日本被四个构造板块包围，相互作用导致地震和火山活动频繁，日本必须保持这样的大地测量基础设施，以接近实时地监测地壳变形，以便可能的减灾。
The Geospatial Information Authority of Japan operates one of the largest GNSS Continuously Operating Reference Station networks in the world, GEONET, consisting of more than 1,300 GNSS-based control points in Japan. GEONET has become a social infrastructure for surveying and mapping, monitoring crustal deformation, and mitigating natural disasters. It is also used for precise positioning to guide construction and farm machines, and even for weather forecasting. Here we review its history and outlook, focusing on its application to disaster mitigation. As Japan is surrounded by four tectonic plates with interactions that lead to frequent earthquakes and volcanic activities, it must maintain such a geodetic infrastructure for monitoring crustal deformations in as near to real-time for possible disaster mitigation.
