UoSAT-5, also known as UoSAT-F, UO-22 and OSCAR 22, is a British satellite in Low Earth Orbit. It was built by Surrey Satellite Technology and launched into space in July 1991 from French Guiana.
UoSAT-5 carries equipment that was similar to that on UoSAT-4, a similar satellite that failed in orbit 1 year previously. The satellite tested new technologies, including validating the performance of Gallium arsenide solar arrays.
