Mission

UoSAT-12 was an experimental mission used to demonstrate and test a number of new technologies. Imaging cameras and a high-speed 1 Mbit/s S-band downlink (the MERLION experiment) were tested. An Internet Protocol stack was uploaded to the satellite, allowing experiments in extending the Internet to space to be made by NASA Goddard as part of its Operating Missions as Nodes on the Internet (OMNI) effort.^[2][3]

These now-proven technologies were later adopted by SSTL in the design of its Disaster Monitoring Constellation satellites.
