PROBLEM TO BE SOLVED: To provide a GPS pseudo distance measurement value with inherent error real-time correction. SOLUTION: In a navigation satellite receiver network, a server is connected to the Internet and provides real-time correction information for a client. The server has a GPS receiver. The GPS receiver can track a group of navigation satellites. When the client is on line, the client can receive information of locations and speeds of the satellites as polynomial equations and coefficients. A clock, an ionizing layer, a convection sphere and other correction values are integrated into one polynomial equation. Accordingly, the client does not need to calculate or use the satellite calendar or the orbit calendar. COPYRIGHT: (C)2005,JPO&NCIPI |
