Abstract: Intelligentization is one of the key themes of current world innovation.We introduce the web of intelligent age: smart sensors and smart sensor web,and discuss the configuration and properties of geoinfo-sensor-web.We also explain the primary intelligence characteristics of GNSS-based continuously operating reference stations(CORS) network and denote the reason that CORS can compose the ground infrastructure of geoinfo-sensor-web.Then we describe the future development and applications of CORS.
