UoSAT-12 was an experimental mission used to demonstrate and test a number of new technologies, including imaging cameras, and a high-speed 1 Mbit/s S-band downlink (the MERLION experiment). 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.
In January 2000, UoSat-12 imaged a lunar eclipse. It also achieved a number of "Firsts" in space - click Discover More.
The satellite platform for the Clementine mission was designed and built by SSTL, and delivered to the prime contractor Thales Alenia for payload integration. The Clementine satellite was part of an intelligence gathering programme for DGA (France) and its mission was to target low frequency electronic signals from targeted regions in the 20 MHz-1 GHz range.
Thai-Paht was the first Thai microsatellite and was launched in 1998 for Mahanikorn University in Bangkok. A team of 12 engineers from the University completed atechnology transfer programme in the UK with SSTL.
FASat-Bravo was the second Chilean experimental microsatellite in orbit, built under a technology transfer program between the Chilean Air Fore and SSTL. The FASat program included the training of Chilenian engineers at SSTL.
FASat-B was a replacement for FASat-A which failed to separate correctly from the primary payload.
FASat-Alpha was the first Chilean experimental microsatellite in orbit, built under a technology transfer program between the Chilean Air Fore and SSTL. The FASat program included the training of Chilenian engineers at SSTL.
FASat-A was launched on August 31, 1995 as a secondary payload to the Ukrainian SICH-1 satellite on a Russian Cyclone-3 vehicle. Unfortunately, the separation mechanism to release FASat-Alpha from SICH-1 failed to operate and some time after the launch, FACh and SSTL declared the spacecraft as lost. The primary payload, SICH-1, was able to perform its observation functions unharmed with the FASat-A permanently attached to it.
Cerise was a French military reconnaissance satellite. Its main purpose was to intercept HF radio signals for French intelligence services.
It was hit by a catalogued space debris object from an Ariane rocket in 1996, making it the first verified case of a collision between two objects in space. The collision tore off a 4.2-metre (13-foot) portion of Cerise's gravity-gradient stabilisation boom, which left the satellite severely damaged, and its performance was compromised.
Healthsat-2 was a commercial digital Store and Forward satellite for medical communications using low cost, portable ground stations.
It was launched on the 25th September 1993, and joined HealthSat-1 (UoSAT-3) as the second SSTL microsatellite in the HealthNet global communications system of SatelLife, a U.S. non-profit organization. HealthNet provided desperately needed low cost 'last mile' communication links between medical institutions and health programmes in the developing world.
PoSAT-1, the first Portuguese satellite, was launched into orbit on September 26, 1993, from the Kourou Space Centre, French Guiana.
PoSAT-1 was an earth observation and technology demonstration mission. It carried two imagers, one with a wide field of view with 2 km ground resolution, the second narrow field imager provided 200m ground resolution. It also carried a Cosmic Ray Experiment and a Digital Signal Processing Experiment.
Launched in 1992, KITSAT-1 was developed through a collaborative program between KAIST and the University of Surrey. The main objective of the KITSAT-1 program was to acquire satellite technology through the training and education of satellite engineers.
The success of the KITSAT-1 program marked the beginning of space technology development for South Korea, who now have their own commercial satellite manufacturer, SaTReC.
UoSAT-5 was launched on the second ARIANE (40) ASAP on mission V44 on the 17th July 1991 alongside three other secondary payloads ORBCOMM-X, SARA and TUBSAT-1, and main payload the European Space Agency's ERS-1.
UoSAT-5 carried a digital Store and Forward communications and Earth Imaging payload, which were enhanced versions of the UoSAT-4 payloads. The spacecraft operated in the amateur satellite communications service providing a research test bed for new and efficient LEO protocols.
The S80/Tmission was sponsored by CNES and carried an experimental VHF transponder manufactured by Dassault and weighing 7kg, for characterising the radio environment in the 148 to 149.9MHz band in preparation for the proposed S80 constellation mobile communications and positioning system.
UoSAT-3 was the first of the SSTL modular microsatellites and it carried a commercial Store and Forward communications payload with 13MByte of solid state storage and VHF and UHF 9600 bps CPFSK links. For the first 18 months it supported amateur service, but when this was taken over by UoSAT-5, it supported VITA, and later SatelLife as HealthSat-1, and Data Trax Inc. (USA).
