SNAP-1 is a British nanosatellite in low Earth orbit. The satellite was built at the Surrey Space Centre by Surrey Satellite Technology Ltd (SSTL) and members of the University of Surrey. It was launched on 28 June 2000 on board a Kosmos-3M rocket from the Plesetsk Cosmodrome in northern Russia. It shared the launch with a Russian Nadezhda search and relay spacecraft and the Chinese Tsinghua-1 microsatellite.
The objectives of the SNAP-1 mission were to:
During deployment, SNAP-1 successfully imaged the Nadezhda and Tsinghua-1 satellites that accompanied it on the launch. Once in orbit, SNAP-1 achieved three axis attitude control, then demonstrated its orbital maintenance capability using its butane cold gas propulsion system.
The 6.5 kilograms (14 lb) SNAP-1 satellite contained the following modules:
