Inclined path ionosphere model with unified reference

The invention discloses an inclined path ionosphere model with a unified reference, and relates to the technical field of satellite navigation precision positioning. The invention discloses an inclined path ionosphere model with a unified reference. The ionosphere model comprises the following steps: S1, extracting an ionosphere observation value with fixed ambiguity; s2, selecting a transmission reference and recovering the ionosphere observed quantity of the non-visual satellite; and S3, modeling the inclined path ionosphere grid. According to the standard-unified oblique path ionosphere model, the ionosphere observed quantity of a recovered non-visual satellite is adopted for complementing. For the ionosphere observed quantity needing to be recovered, the ionosphere delay quantity of the same satellite of the nearest neighbor station is selected as approximation, the influence of receiver deviation is considered, unification of receiver deviation references is achieved by selecting a plurality of transfer
