The invention relates to a fast and accurate centimeter-level single point positioning method, so as to solve the problems that the existing satellite positioning system is poor in positioning accuracy, long in positioning time and largely influenced by weather and position factors. According to the technical scheme for the fast and accurate single point positioning method of the invention, a multi-band antenna is used for receiving a multisystem navigation message and interstellar differential correction data, a receiver initially processes and coverts the navigation message and the correction data to coordinates in a WGS84 coordinate system, and a control system carries out joint solution on the coordinate data to acquire accurate positioning data. The method has the beneficial effects that coordinate measurement with the accuracy within 10cm in 30 minutes in a condition with no blocking around can be realized, and defects of the market are remedied.
