Satellite Positioning Method and Satellite Positioning System

A satellite positioning system, comprising:

• a satellite, a base station, an observation station,
• the observation station being provided with a monitoring terminal and a correction parameter information generating apparatus,
• the monitoring terminal receiving observation data transmitted from the satellite;
• the device for generating correction parameters information generating apparatus generating correction parameters for enhancement, based on the received observation data, the correction parameters being transmitted to the base station,
• the base station being provided with a switch and a message parameter superimposition-encoding-and-broadcasting apparatus for message parameter superimposition, encoding and broadcasting of message parameter,
• the switch receiving a basic navigation message from the satellite;
• the message parameter superimposition-encoding-and-broadcasting apparatus encoding the correction parameters into the basic navigation message by protocol superimposition, and setting the broadcasting of the integrated-encoded message into which the correction parameters is encoded, the integrated-encoded message being transmitted to the satellite by the switch via an uplink injection link,
• the satellite broadcasting the integrated-encoded message received from the base station, wherein,
• the correction parameters comprises a partition comprehensive correction and one or more of a satellite orbit correction, a satellite clock difference correction, and an ionosphere correction.
