Abstract: The present application provides a satellite positioning method and a satellite positioning system. The system includes a satellite, a base station, an observation station. The observation station is provided with a monitoring terminal and a correction parameters information generating apparatus, the monitoring terminal receiving observation data transmitted from the satellite; the correction parameters information generating apparatus generating a correction parameters based on the observation data, the correction parameters being transmitted to the base station.

Abstract: A zone correction-based method for improving positioning accuracy in a satellite-based augmentation system, including: dividing an area to be observed into a plurality of observation areas, and configuring a plurality of monitoring stations in each observation area; acquiring residual of each monitoring station by processing observation data; acquiring mean clock error value of each monitoring station according to observation residual; acquiring ambiguity reduction value of each observation area according to residual data; acquiring zone corrections of each observation area according to residual data and ambiguity reduction value data; and providing a user with a zone corrections calling service by means of a network or a satellite link. The method carries out wide-range area configuration to monitoring stations and calculates the zone corrections for use in network and satellite-based broadcasts on the basis of the monitoring stations to refine error correction in user positioning.
