As part of the Astrium-led Earth Observation (EO) Hub project at the International Space Innovation Centre (ISIC) in Harwell, small satellite pioneer Surrey Satellite Technology Ltd. (SSTL) has completed the installation of key groundstation equipment. This comprehensive new system provides everything needed to plan mission operations, communicate with the satellites and downlink the images and other information for a broad spectrum of missions. It will initially be used to operate the SSTL-built TechDemoSat-1 satellite, which is being developed through a grant from the U.K.’s Technology Strategy Board (TSB), and planned to be launched next year.
Satellites are tasked from the Mission Operation Centre using the Mission Planning System (MPS). For example, for an imaging mission, a user can program where and when an image should be acquired days — or even weeks — in advance. This “tasking” of the spacecraft and the subsequent image acquisition is highly automated helping to reduce the cost of the operations. After the missions are planned, the Spacecraft Operations Centre will track the satellites as they orbit Earth, automatically managing each satellite as it passes. The highly automated systems orientate the antenna, download telemetry data and provide spacecraft control and analysis functions to operator workstations.
