HYLAS 1 will bring high-speed broadband services to remote rural areas across Europe, using its ‘highly adaptable’ payload, developed by Astrium, primarily at its UK sites in Portsmouth and Stevenage.
The payload is designed to allocate varying amounts of power and bandwidth to the different regions within its footprint, reacting to traffic demand.
Over the past four weeks, HYLAS 1 has undergone a series of thermal-vacuum (TVAC) tests at the Indian Space Research Organisation (ISRO) in Bangalore, which is responsible for the satellite’s platform and satellite integration.
Engineers from Astrium and ISRO tested the satellite’s payload electronics and external structures in temperatures ranging from −30°C to +80°C, which are representative of conditions that the satellite will have to endure in orbit.
Integration of the Ka antenna feed has also been completed, which will validate Astrium’s Single Feed Per Beam (SFPB) design and its incorporation into a thermally compensated structure.
HYLAS 1 will cover rural areas of western and central Europe that are unlikely to receive any terrestrial broadband within the next 10 years. The payload will provide broadband services for up to 350,000 users.
The UK Space Agency and Technology Strategy Board has provided support for the development of HYLAS 1 through the UK subscription to the European Space Agency ARTES programme.
