On Construction of Continuous Operation Reference System for Differential GPS Satellite Navigation and Positioning

Establishing a continuous operation reference system (CORS) for satellite navigation and positioning is the inevitable tendency in further developing and exploring GPS technique application. This paper mainly describes the structure and technical indexes of CORS, and analyzes critical techniques of the system. It also presents the structure design of CORS combing a practice of establishingthe CORS in cityC. Operation experiments in practice showthe feasibility and effectiveness of the system.
