Raspberry Pi video of Europe from DoT-1 satellite

Video of the Earth captured from Low Earth Orbit by a commercial grade Raspberry Pi camera and computer on board SSTL's Demonstration of Technology satellite called DoT-1, launched in July 2019. The video captures an area of Europe that includes the coasts of France, Belgium, The Netherlands and Germany with Denmark visible to the right and the UK obscured by heavy cloud cover to the left.

NovaSAR-S animation

NovaSAR-1 was launched in 2018 and delivers Earth observation Synthetic Aperture Radar imagery, day and night and through cloud cover. NovaSAR data partners include the UK Space Agency, CSIRO (Australia), ISRO (India) and DOST-ASTI (the Philippines).  


Video showing the construction of the platform for EUTELSAT QUANTUM, the world's first reconfigurable geostationary telecommunications satellite.  The platform consists of a central thrust tube which houses the bipropellent chemical propulsion system, GEO momentum wheels and gyro to maintain the satellite on station and in a stable attitude throughout its orbital lifetime.

SSTL DMC3 / TripleSat Constellation

Assembly and integration at Surrey's Guildford facilities of three one metre resolution earth observation satellites for the DMC3/TripleSat Constellation.

TechDemoSat-1 video from orbit

This video video was taken in-orbit on 8 July 2014 using an inspection camera on-board ourTechDemoSat-1 satellite, starting about 30 seconds after separation from the launcher. At 6 seconds the Sun appears at the top of the frame as a very bright white flare, before the rotation of the satellite reveals a view of Earth below, of the Pacific Ocean south of French Polynesia. At 25 seconds, the Fregat upper stage of the Soyuz-2 launch vehicle appears as a gold object passing left to right at a distance of approx 60 metres. At 34 seconds a white dot crosses the frame left to right - this is almost certainly one of the other satellites that shared the ride into orbit with TechDemoSat-1.

TechDemoSat-1 video from orbit

Video taken in orbit by a small inspection camera on board TechDemoSat-1 (June 2017). The camera is trained on the Antenna Pointing Mechanism, and also captures views of the Earth - this footage shows Greenland, travelling south to Baffin Bay.
