Abstract
Precise point positioning (PPP) method and a PPP device are provided. The precise point positioning method includes obtaining a first satellite signal of a target satellite and a second satellite signal of a reference satellite. The first satellite signal and the second satellite signal are combined to eliminate a signal error and obtain a combined satellite signal. A smoothing process is performed on a code data of the combined satellite signal, to obtain a satellite positioning data for positioning process. The satellite positioning data includes modified code data and modified carrier-phase data.
