The invention discloses an early warning method and early warning system for a surface charging effect of a geosynchronous orbit satellite. The early warning method comprises the steps of: acquiring AE index data at a T0 moment; calculating the local time of the satellite corresponding to the AE index moment; calculating a surface charging potential mode calculation value U of the geosynchronous orbit satellite according to the AE index data; obtaining a surface charging index ISC according to the surface charging potential mode calculation value U; and carrying out early warning against a satellite surface charging dangerous situation according to the surface charging index ISC. The method provided by the invention can effectively provide reliable data support for possible surface charging effects, and also has a reference effect on analysis and disposal of the anomalies of the satellite.
