Abstract
A terminal Global Positioning System (TGPS) adopting a real-time self Differential Global Positioning System (DGPS) is developed for positioning a moving station in a local area. This TGPS enables not only to minimize the error ranges without any additional expensive transmitting-receiving equipment, but also to calculate an accurate correcting value through a TGPS server. A method of TGPS adopting the real-time self DGPS comprises the steps of: (1) receiving a GPS signal from the moving station containing data of satellite time and pre-measured moving station position, (2) receiving the reference station GPS signals at the TGPS server (3) calculating a correcting value from the moving station at the central control server, (4) calculating an error-corrected real position of the moving station according to the correcting value and position data of moving station at the central server, and (5) positioning the moving station accurately according to the correcting value and the GPS signal of the moving station at the central control server.
