Three-axis agility for a satellite that fits in your hands.

At 142 g, the RW20 is the smallest reaction wheel Comat builds and one of the few in its class to arrive flight-proven, with embedded electronics already inside. No external driver board, no integration overhead: connect power and RS 422/485, and your CubeSat starts pointing.

It delivers 20 mNms of momentum and 2 mNm of torque with control resolution down to 1 rpm, so fine pointing is no longer a trade-off you accept on small platforms.

Need full three-axis authority? The four-wheel cluster packs redundant control into 95 x 95 x 61 mm for 850 g.

Designed, qualified and manufactured in Toulouse under EN9100.
Recognised in the NASA State-of-the-Art of Small Spacecraft Technology.
