Abstract:
The Colour and Stereo Surface Imaging System (CaSSIS) is the main
imaging system onboard the European Space Agency's ExoMars Trace Gas
Orbiter (TGO) which was launched on 14 March 2016. CaSSIS is intended to
acquire moderately high resolution (4.6 m/pixel) targeted images of Mars
at a rate of 10-20 images per day from a roughly circular orbit 400 km
above the surface. Each image can be acquired in up to four colours and
stereo capability is foreseen by the use of a novel rotation mechanism.
A typical product from one image acquisition will be a swath in full
colour and stereo in one over-flight of the target thereby reducing
atmospheric influences inherent in stereo and colour products from
previous high resolution imagers. This paper describes the instrument
including several novel technical solutions required to achieve the
scientific requirements.
