SPOT Earth surface satellite observation system (Satellite Pour L’Observation de la Terre) is engineered by the National Space Agency of France in cooperation with Belgium and Sweden. SPOT includes a number of space-based and ground facilities intended for satellite control, data collection programming, data acquisition and image drawing. SpotImage Company (France) is an operator of the satellite.
SPOT-2 was launched on January 21, 1990 in sun-synchronous orbit at the height of 825 km.
SPOT-4 spacecraft was launched on March 24, 1998 and placed in sun-synchronous orbit with altitude of 822 km. In comparison with preceding SPOT satellites, SPOT-4 has an additional short-wave infrared band which allows detecting surface type. SPOT-4 is equipped with daughter payload VEGETATION1 apparatus, jointly engineered by European Union, Belgium, Italy and Sweden. Estimated period in orbit is 5 years at least.
