Abstract: A method for mitigating interference in a satellite communication system includes initializing, by a processing system, a predictive analysis window prior to scheduled ground pass to evaluate a downlink trajectory of a target satellite. The method includes querying a satellite catalog management entity (SCME) maintaining database of active satellite assets cataloging transmission parameters including carrier frequencies, operational frequency bands, modulation types, coding schemes, bandwidth envelopes, and orbital state vectors. The method includes executing a three-dimensional line-of-sight intersection algorithm to predict whether any non-target spacecraft will transit through primary antenna beamwidth or sidelobes of designated ground stations during an active pass window. The method includes synthesizing an interference characterization vector by processing SCME metadata through live atmospheric conditions, injecting the vector into cloud-native software-defined radio (SDR), and applying an adaptive digital filter to subtract predicted interference signature from a raw digital I/Q stream to isolate a signal of the target satellite.
