As part of its research program in space mission analysis & design, and proposed CubeSat operations, the Royal Military College of Canada (RMCC) Center for Space Research (CSR) has developed an amateur satellite communication ground station. The ground station has been implemented to support staff and student research, teaching and learning opportunities in communications, and in support of high altitude balloon and CubeSat design, testing, and operations

*GENSO: ICOM computer Control Interface (ICOM CI-V) radios allow multiple radio control simultaneously and are required ground station hardware for participation in the Global Educational Network for Satellite Operations (GENSO).
Introduction OverviewVE3RMC has been composed of relatively low-cost, small scale equipment enabling communications with OSCAR-class satellites in the 2m and 70cm wavelength radio bands. It is hoped the VE3RMC station may support, command, and control future RMCC CubeSats upon their successful launch into orbit. As RMCC does not have an active satellite at this time to downlink data and uplink commands the primary users of the VE3 RMC ground station are students obtaining communications and satellite contact experience. Additionally high altitude balloon communications and navigation (tracking) training may be performed prior to launch using ground station software for Automatic Packet Reporting System (APRS) equipped aircraft.
