Abstract
The Space Innovations Limited SGS-2.4 ground station is a flexible low-cost system designed specifically for small satellite missions in a low Earth orbit using S- and X-band communications links. The ground station is compatible with ESA and NASA communications standards. These features, as well as its high tracking speeds, make the system widely compatible and capable of supporting many mission types. The paper describes the overall system configuration and covers the mechanical design of the antenna and its drive system. © IMcchE 1999.
