The SPOT constellation are owned and operated by SPOT Image based in Toulouse, France and collect image data down to a pixel resolution of 10 m.
SPOT (Satellite Pour l'Observation de la Terre) 1, 2, 3 and 4 are high resolution satellites that were launched in 1986, 1990, 1993 and 1998 respectively. The SPOT constellation are owned and operated by SPOT Image based in Toulouse, France and collect image data down to a pixel resolution of 10 m.
Onboard sensors can point across the satellite track, providing a revisit capability of 1-4 days depending on latitude. The satellites capture both panchromatic (black & white) and multispectral (colour) digital imagery. SPOT 4 & SPOT 5 are the only active satellites in this constellation at the moment.
