An unmanned aircraft system (UAS) control apparatus is disclosed. In embodiments, the UAS control apparatus is embodied in a control station to manage command and control (C2) functions for UAS operations in a designated coverage volume including a geofenced interference region proximate to the control station, controlling each UAS via connections on a spectrum of C2 channels. The UAS control apparatus generates flight plans for UAS operations, providing separation and keeping UAS operations away from the control station to minimize RF interference with other UAS C2 connections. Should a UAS be required to operate proximate to the control station, the UAS control apparatus employs dynamic spectrum management with respect to other concurrently operating UAS to eliminate, reduce, or mitigate RF interference resulting from the encroaching UAS.
