Telecom Satellite Mechanical Platform

Astrium and its partners are designing a new mechanical backbone for European telecommunications satellites weighing between 3 and 6 tonnes. The mechanical platform—the satellite’s structure, propulsion system, and thermal control—currently limits how much communications equipment a satellite can carry and how efficiently it can manoeuvre in orbit. This project studies alternative architectures that better fit the payload’s needs and improve propulsive efficiency. It is the first stage of a wider European effort to develop a Next Generation Platform, and it aims to strengthen the UK supply chain’s competitiveness in satellite manufacturing. If successful, the new platform could allow satellites to carry more powerful transponders or operate longer on less fuel. That matters for everyday communications: satellite TV, broadband internet, and secure military links all depend on these spacecraft. A more efficient platform also reduces launch costs and orbital debris risks. The project is applied engineering, not fundamental science—its value lies in making existing satellite technology lighter, cheaper, and more capable for the next generation of telecoms infrastructure.
