Telecommand Encoder Shell on STRV Mission
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-1A and -1B are small (50kg), low-cost research satellites to investigate 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 (DERA), Farnborough, UK.
STRV-1A and -1B implement CCSDS Packet Telecommand and Packet Telemetry standards. Space Technology Systems Limited (STS) was the contractor to DERA for development of the ground data processing equipment, consisting of a number of personal computers. The processing included the support for Packet Telecommand.
STS used the Telecommand Encoder Shell package supplied by I.B.+ M.A. de Lande Long Software and Consultancy.
