Svalbard Satellite Station or SvalSat is a satellite ground station located on Platåberget near Longyearbyen in Svalbard, Norway. Opened in 1997, it is operated by Kongsberg Satellite Services (KSAT), a joint venture between Kongsberg Defence & Aerospace and the Norwegian Space Centre (NSC). SvalSat and KSAT's Troll Satellite Station (TrollSat) in Antarctica are the only ground stations that can see a low altitude polar orbiting satellite on every revolution as the Earth rotates. As of 2021, the facility consists of 100 multi-mission and customer-dedicated antennas which operate in the C, L, S, X and K bands. The station provides ground services to more satellites than any other facility in the world.
