SNAP-1 (2000)

The first successful use of GPS on board a nanosatellite for orbit manoeuvring, SNAP-1 (2000)

Although SNAP-1 was less than 7 kg, it carried a SGR-05 GPS receiver, a butane propulsion system and a camera. The GPS receiver was used to update the orbit as the propulsion system raised the orbit by 2.5 km in a rendezvous experiment.
