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 positioning.
