Tromsø Satellite Station

Tromsø Satellite Station (Norwegian: Tromsø Satellittstasjon, TSS), until 1988 known as Tromsø Telemetry Station (Norwegian: Tromsø telemetristasjon), is a satellite earth station located in Tromsø, Norway. The facility is owned by Kongsberg Satellite Services (KSAT), a joint venture between the Kongsberg Group and the Norwegian Space Centre (NSC). In addition to hosting its own antennas serving thirty satellites, TSS acts as the center-point of KSAT's operations and provides backbone services for the high Arctic Svalbard Satellite Station (SvalSat) and the Antarctic Troll Satellite Station (TrollSat).

Originally proposed in 1965, the station was established by the Royal Norwegian Council for Scientific and Industrial Research (NTNF) in 1967 in close cooperation with the Norwegian Defence Research Establishment (NDRE) and located adjacent to Tromsø Geophysical Observatory. From its inception until 1974, it served low-Earth orbit (LEO) satellites operated by the European Space Research Organization (ESRO). To a lesser extent it was also used by Canadian Space Agency and National Aeronautics and Space Administration (NASA) LEO satellites. Norway's non-membership in ESRO and later the European Space Agency (ESA) caused Tromsø to not become a ground station for Landsat. A gradual increase in operations occurred from 1982, such as for the International Cospas-Sarsat Programme and the European Remote-Sensing Satellite. TSS became part of NSC in 1990, although it was partially sold to the Swedish Space Corporation (SSC) in 1995. SvalSat merged with TSS in 2002 to form KSAT.
