help Pleiades 1A FAQ
Who operates the Pleiades 1A satellite?
Pleiades 1A is operated as part of a joint program between CNES (the French space agency) and Airbus Defence and Space. The satellite serves both defense and civilian Earth observation needs for France and allied users.
When was Pleiades 1A launched?
Pleiades 1A was launched in December 2011. It was joined by its twin satellite, Pleiades 1B, launched in December 2012, forming a two-satellite constellation for high-resolution imaging.
What type of imagery does Pleiades 1A capture and from what orbit?
Pleiades 1A captures very high-resolution optical imagery from a sun-synchronous polar orbit. This orbit allows it to pass over any point on Earth at consistent local solar time, providing uniform lighting conditions for imaging.
What is Pleiades 1A imagery used for?
Pleiades 1A imagery supports defense, agriculture, environmental monitoring, urban planning, and disaster response applications. The very high-resolution optical capability allows users to distinguish fine ground-level details from orbit.
