More Information
Summary:A terminal positioning method includes: obtaining a positioning information set for a terminal at a first moment; providing an estimated motion state of the terminal at the first moment; obtaining measurement data of signal measurement performed by the terminal on a satellite, and estimating an error of positioning information corresponding to the satellite; obtaining converted positioning information converted from the estimated motion state, to calculate deviation information between the positioning information and the converted positioning information, and determining an error adjustment factor of the satellite; providing a predicted motion state of the terminal at the first moment through a state prediction model; applying the positioning information set, the error, and the error adjustment factor to the state adjustment model to obtain an adjusted motion state of the terminal at the first moment; and determining a positioning result of the terminal at the first moment according to the adjusted motion state.
