Why did one of the world’s premier space communication gateways, Goonhilly Earth Station, choose to upgrade its deep-space satellite dish with Sprint Electric digital DC drives, rather than opting for AC alternatives?
The overall project objective was to renovate a deep-space antenna to create a whole new control platform. This involved undertaking an extensive upgrade of the dish, including overhauling both the radio equipment and the motor drive system.
