Surrey Satellite Technology Ltd, or SSTL, is a spin-off company of the University of Surrey, now majority-owned by EADS Astrium, that builds and operates small satellites. Its satellites began as amateur radio satellites known by the UoSAT (University of Surrey SATELLITE) name or by an OSCAR (Orbital Satellite Carrying Amateur Radio) designation. SSTL cooperates with the University's Surrey Space Centre, which does research into satellite and space topics.
SSTL moved into remote sensing services with the launch of the Disaster Monitoring Constellation (DMC) in 2002 and an associated child company, DMC International Imaging. SSTL also adopted the Internet Protocol for the DMC satellites it builds and operates, migrating from use of the AX.25 protocol popular in amateur radio. The CLEO Cisco router in Low Earth Orbit, on board the UK-DMC satellite along with a network of payloads, takes advantage of this adoption of the Internet Protocol. SSTL is also developing a new Geostationary Minisatellite Platform-Transfer orbit variant (GMP-T) aimed at the telecommunications market under the brand name SSTL-900.
The University sold a 10% share of SSTL to SpaceX in January 2005. It then agreed to sell its majority share (roughly 80% of the capital) to EADS Astrium in April 2008.〔(EADS Astrium signs an agreement to acquire Surrey Satellite Technology Limited from the University of Surrey ), press release, 7 April 2008.〕 In August 2008 SSTL opened a US subsidiary.〔(Surrey Satellite Technology US opens for business ), SSTL press release, 5 August 2008.〕
SSTL was awarded the Queen's Award for Technological Achievement in 1998, and the Queen's Awards for Enterprise in 2005. In 2006 SSTL won the Times Higher Education Supplement award for outstanding contribution to innovation and technology.〔(SSTL wins ''Times Higher award'' ), 16 November 2006.〕
In 2009 SSTL ranked 89 out of the 997 companies that took part in the ''Sunday Times Top 100 companies to work for''.〔(SSTL earn Sunday Times Award ), SSTL space blog, 17 MArch 2009.〕

:Mission objective: To provide a satellite-based Resident Space Object (RSO) observing service that will provide accurate tracking data on deep space orbiting objects. Sapphire is the Canadian Department of National Defence's first dedicated operational military satellite. Its space-based electro-optical sensor will track man-made space objects in Earth orbits between 6000 and 40,000 km as part of Canada's continued support of Space Situational Awareness and the U.S. Space Surveillance Network by updating the U.S. Satellite Catalogue that is used by both NORAD and Canada.〔(SSTL's 40th satellite platform launch: Sapphire reaches orbit ), SpaceDaily.com, 26 February 2013〕
