The SNAP-1 nanosatellite was the UK's first nanosatellite in orbit and was designed to develop a modular, multi-mission nanosatellite bus (mass range of 10-10kg), to demonstrate the use of miniature electrical and mechanical COTS product technologies in space, and their use as autonomous robots for observing orbiting spacecraft.
SNAP-1 mission achievements:
- The first fully 3-axis attitude stablised nanosatellite.
- The first nanosatellite with on-board propulsion demonstrating orbit control.
- The first in-orbit images of another spacecraft from a nanosatellite.
- The first successful use of GPS on-board a nanosatellite - used for orbit manoeuvring
- First use of propulsion on a nanosatellite and first use of butane as a space propellant
