The Telecommand Encoder Shell has been operational software since June 1994 when the STRV-1A and STRV-1B satellites were launched into geostationary transfer orbit by an Ariane 44LP.
The Space Technology Research Vehicles (STRV-1A and STRV-1B) are small (50kg), low-cost research satellites designed to investigate the in-orbit performance of new space technologies (radiation damage to components, alleviation of electrostatic charging, corrosion, new materials). These technologies are aimed at improving the performance, lifetime and overall cost-effectiveness of future space missions. STRV was developed by the Space and Communications Department of the Defence Evaluation and Research Agency, Farnborough, UK.
STRV-1A and -1B implemented the CCSDS packet telecommand and telemetry recommendations and a ground segment was developed by DERA to support these recommendations. Space Technology Systems Limited (STS) was the major ground segment contractor to DERA and developed a number of the data processing subsystems, including support for CCSDS packet telecommand. The ground data processing equipment consisted of a number of personal computers.
STS used the Telecommand Encoder Shell package supplied by I.B.+ M.A. de Lande Long Software and Consultancy.
