Sweden's Odin scientific satellite carried a submillimeter wave astronomy instrument and a radiometer for atmospheric studies. The 1.1-meter reflector fed 500 GHz and 119 GHz radiometers and was used to study galactic molecular clouds, complementing NASA's SWAS satellite. The Odin satellite was designed and built by the Swedish Space Corporation (Svenska Rymdbolaget or Rymdaktiebolaget). SSC does most of its satellite design and construction in-house, although Saab made the antenna and carried out satellite final assembly. SSC was a goverment-owned company and a contractor for the Rymdstyrelsen (Swedish National Space Board).
