TopSat: Launched 2005

TopSat was designed to use controlled spacecraft manoeuvres to increase the exposure time of images. This ensured high-resolution images could be obtained, even in poor light. The single instrument on board is an imager collecting 17 x 17 km images of the earth with a panchromatic (black and white) resolution of 2.5 metres and a multispectral (colour) resolution of 5 metres.  The camera was designed at STFC Rutherford Appleton Laboratory.
