A disruptor satellite is a planet-defending version of the smaller Replicator disruptor, designed to disintegrate Replicator vessels on a planetary scale. The disruptor itself was based on Ancient technology, although the Asgard were able to adapt it for their own uses. The satellite was compatible with human computers and could be remodulated to target Replicator ships who had made themselves immune to previous attacks by the technology. This remodulation could occur while the satellite was in orbit.
