It was built by a spin-off company of the University of Surrey, Surrey Satellite Technology (SSTL) and launched in January 1990 from French Guiana.[1] The satellite functioned as one of a series of OSCAR satellite in orbit around the Earth, as well as observing Earth and performing scientific experiments.[2] UoSAT-3 was launched on the same rocket as its sister satellite, UoSAT-4.[2] Current StatusUoSAT-3 exceeded its expected operational life by 3 years and ceased active service in 1999.[3] However, amateur radio enthusiasts managed to track the satellite for a certain amount of time afterwards via the satellite's FM voice transponder.[3] The satellite, which is now non-operational, forms a part of the growing amounts of space debris orbiting around the Earth. The payload will decay in the Earth's atmosphere some time in the future. {{-}}References{{Portal|Spaceflight}}1. ^1 {{cite web|title=Sat Cat|url=http://celestrak.com/satcat/1990/1990-005.asp|publisher=Celestrak|accessdate=27 June 2012}} {{UoSAT}}{{Orbital launches in 1990}}{{Amateur-radio-stub}}{{UK-spacecraft-stub}}2. ^1 2 {{cite web|title=UoSat 3, 4, 5 (UO 14, 15, 22 / Oscar 14, 15, 22) / Healthsat 1|url=http://space.skyrocket.de/doc_sdat/uosat-3.htm|publisher=Gunter's Space Page|accessdate=27 June 2012}} 3. ^1 {{cite web|title=Messages from Space|url=http://www.ph.surrey.ac.uk/satellites/main/where_are_they2.html|publisher=University of Surrey|accessdate=27 June 2012}} 4 : University of Surrey|Amateur radio satellites|Satellites of the United Kingdom|Spacecraft launched in 1990 |
