Disturbance detection-oriented residual ionosphere chromatography method, device and medium

The invention belongs to the technical field of ionosphere chromatography in the field of GNSS ionosphere inversion, realizes inversion of three-dimensional space-time distribution of electron density change when ionosphere disturbance occurs, and solves the problems of three-dimensional inversion of electron density abnormal variation, non-uniform distribution of ground observation stations, non-combination of an iterative algorithm with actual electron distribution and the like. According to the disturbance detection-oriented residual ionosphere chromatography method, the disturbance detection-oriented residual ionosphere chromatography device and the medium, virtual observation values are obtained by arranging virtual observation stations, the virtual observation stations are arranged in an area with sparse inversion area stations, virtual puncture points are calculated according to connecting lines of the virtual stations and GNSS satellites, and the virtual observation values are calculated according to
