Programme details
Programme description
Series of seven operational satellites for high-resolution land observation.
USA programme: NASA responsible of the development of the space segment, USGS responsible of mission requirements definition, development of the ground segment and full system operation.
The platforms are actively stabilised over 3 axes.
The design life time of the satellites was 3 years for the earlier flights units, progressively increased up to 7 years for the last unit.
The satellites exploit geosynchronous orbits around 10:00.
The replacement policy is based on launching satellites in sequence, roughly 6 months before the expected end-of-life of a satellite.
