A time‐variant total electron content (TEC) estimation method with fully polarimetric geosynchronous synthetic aperture radar (GEO‐SAR) data is proposed based on inner aperture Faraday rotation angle estimation and an accurate TEC inversion model. With a long integration time and sensitivity to ionosphere effects, the fully polarimetric GEO‐SAR data are utilised for estimation with high accuracy for both the time‐variant TEC and the time interval. Superiority of the proposed method over conventional ionospheric sounding methods is verified by simulation results.
