| Abstract: | In view of the existing problems in the construction of various regional continuously operating reference stations (CORS),the concept,characters and foundations of large-scale CORS were elaborated.Then,based on Grid computing technology,its architecture,data collect method,mode of data processing and severing were proposed in detail.At last,the concept of Virtual CORS(VCORS) was put forward,and its services cruise and seamless transform was discussed,a preliminary solution was proposed. |
