SADM

Small Sat

Product

The SADM-200 (Solar Array Drive Mechanism) has been developed by COMAT for satellites with up to 200W by solar array wing. This very compact mechanism allows accommodation on small satellites with an integrated slip ring. This equipment is delivered with embedded plug & play electronics.

The second version, SADM 1500, will be able to handle 1500W per solar array wing. Currently under development, its qualification is expected for S1 2025.

Main benefits

This equipment optimizes the exposure of solar panels, particularly on Earth observation platforms. This development is based on bricks already developed by COMAT as part of its product development.

We qualify this SADM for 200W of power at 28V. However, at 50V this equipment can transfer up to 400W.

This SADM is the only European off-the-shelf solution for satellite platforms requiring more power.
