| Abstract: | The accuracy of geolocation on meteorological satellite data is critical for its application.The geolocation error sources of polar-orbit satellite are introduced,and then the research status on geolocation error estimation and correction is reviewed.Three mathematical methods of geolocation error correction,including Coastline Crossing Method (CCM),Node Differential Method (NDM) and Land Sea Fraction Method (LFM) are compared and discussed.Future researches in geolocation error correction are prospected. |
