Self-adaptive grid point VRS correction number generation method

The invention discloses a self-adaptive grid point VRS correction number generation method, which comprises the following steps of calculating atmospheric grid point coordinates through a real-time regional atmospheric delay model and an atmospheric error threshold value, and generating a single-difference ionosphere delay correction number and a single-difference troposphere delay correction number according to atmospheric grid point coordinate interpolation; according to preset geometric grid point coordinates, geometric distance correction numbers of all grid points are generated in sequence; and generating a VRS correction number of each grid point according to the single-difference ionosphere delay correction number, the single-difference troposphere delay correction number and the geometric distance correction number. The problems that in the prior art, positioning reliability is low, the positioning effect is poor, and a high-dynamic user can face frequent initialization are solved. 本发明公开了一种自适应网格点VRS改正
