Abstract: The present invention provides a message broadcast apparatus and method for enhanced parameters in a satellite navigation system. The apparatus includes: a processor, which determines the insertion position of the enhanced parameter in the reserved space in the navigation message frame structure model according to the byte size and the broadcast frequency of the enhanced parameter that needs to be broadcast, so as to perform the message arrangement of the enhanced parameter; and a transmitter, which uploads the arranged message to the broadcast satellite for broadcasting the message.

Abstract: The present application provides a method for navigation and positioning of a receiver, including: receiving basic broadcast messages and correction parameters of a plurality of satellites, and establishing a pseudorange observation equation and a carrier-phase observation equation corresponding to each of satellites respectively; correcting the pseudorange observation equation and the carrier-phase observation equation using the received correction parameters to obtain the corrected pseudorange observation equation and the corrected carrier-phase observation equation; constructing a first observation according to the corrected pseudorange observation equation and the corrected carrier-phase observation equation; constructing a second observation according to the corrected pseudorange observation equation and the corrected carrier-phase observation equation; and jointly solving the obtained first observations and second observations of the plurality of satellites to obtain anoperation result of user positioni

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.
