Surrey Satellite Technology Ltd. (SSTL) is a spin-off company of the University of Surrey, now fully owned by Airbus Defence and Space, 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 funds research projects with the University’s Surrey Space Centre, which does research into satellite and space topics.
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. In August 2008 SSTL opened a US subsidiary which it closed in 2017.
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. In 2009 SSTL ranked 89 out of the 997 companies that took part in the Sunday Times Top 100 companies to work for.
