Skynet 6A Passes Preliminary Design Review

Airbus has successfully completed the first key phase of the Skynet 6A project with the achievement of the Preliminary Design Review (PDR).

The project now has permission to move into the next phase leading to the Critical Design Review (CDR).

Airbus was awarded the Skynet 6A contract in July 2020 and teams across its sites in Stevenage, Portsmouth and Hawthorn have been working on the programme to achieve this key milestone. Meetings with the UK Ministry of Defence (MOD) were held virtually enabling the review board to take place in October and the PDR being achieved in November.

Richard Franklin, Managing Director of Airbus Defence and Space UK said: “This is excellent news and demonstrates our joint commitment to work in partnership to achieve the programme schedule. The progress we are making in building the UK MOD’s next generation military satellite and getting to this stage, despite current restrictions, really highlights the flexible and strong working relationship we have built with the Defence Digital team. Skynet 6A, to be built entirely in the UK, will significantly enhance the UK’s milsatcoms capability, building on the heritage of the four Skynet 5 satellites which were also built by Airbus, and which are all still operating perfectly in orbit.”

Teams from across the space and ground segments in Airbus worked closely with their MOD counterparts to keep the programme on track.

Skynet 6A will extend and enhance the Skynet fleet. The contract signed with the UK MOD in July 2020 involves the development, manufacture, cyber protection, assembly, integration, test and launch, of a military communications satellite, Skynet 6A, planned for launch in 2025. The contract also covers technology development programmes, new secure telemetry, tracking and command systems, launch, in-orbit testing and ground segment updates to the current Skynet 5 system. The value of the contract is more than £500 million.

The Skynet 6A satellite is based on Airbus’ Eurostar Neo telecommunications satellite platform. It will utilise more of the radio frequency spectrum available for satellite communications and the latest digital processing to provide both more capacity and greater versatility than Skynet 5 satellites.

The satellite will feature electric orbit raising propulsion as well as electric station keeping systems for maximum cost effectiveness. Complete satellite integration will take place at Airbus facilities in the UK followed by testing using RAL Space testing facilities at Harwell in Oxfordshire supporting the UK Space Agency initiative for sovereign UK end-to-end satellite production and support.

The satellite is due for launch in 2025, and will have a minimum design lifetime of 15 years.
