Pleiades 1А/В

The Pleiades High-Resolution program has been part of the European remote sensing satellite system and has been operated by the French space agency CNES since 2001. It includes two new generation ultra-high resolution satellites, Pleiades-1A and Pleiades-1B with the same technical characteristics. The satellites are synchronized in one orbit to be able to provide a daily image of a certain area of the earth’s surface.

Briefly about the main thing

Using next-generation space technology, the Pleiades-1A and Pleiades-1B spacecraft have unprecedented maneuverability. They can shoot anywhere on an 800-kilometer strip in less than 25 seconds with a geopositioning accuracy of less than 3 m (CE90) without the use of ground reference points and 1 m with the use of ground points.

To continue the Pleiades mission, Airbus Defense and Space plans to launch 4 ultra-high-resolution optical satellites in 2020-2021.Compared to existing satellites, the technical characteristics will be significantly improved to meet the growing demands of the market, providing solutions to new challenges for business and analytics.
