Observing Systems Capability Analysis and Review Tool
Satellite Programme: Pléiades
Constellation of two satellites in orbits coordinated so as to provide frequent revisit time (up to daily with both satellites in orbit).
Follow-on and merging of the civilian SPOT and military Helios series.
CNES responsible of development and operations, with national contributions from Sweden, Belgium, Spain and Austria. Programme coordinated with the ASI COSMO-SkyMed to implement the Optical and Radar Federated Earth Observation programme (ORFEO).
The platforms are actively stabilised over 3 axes.
The design lifetime of the satellites is 5 years.
The satellites exploit a sunsynchronous orbit around 10:30.
The two-satellite programme implies mutual redundancy. Further redundancy is provided by the co-flying SPOT-6 and SPOT-7.
