COMAT is developing a SADM (Solar Array Drive Mechanism) to notably increase solar panel exposure on Earth observation platforms.  This development relies on the bricks already developed by COMAT for its products.

Indeed, the main innovation of this product relies on the use of industrial components that meet the constraints of the space environment and are compatible with its life span.

 

This SADM (200W) is the only European off-the-shelf solution for satellite platforms needing more power. Qualification is expected in 2022.
