HR04, HC7 & HC9 REACTION WHEEL ASSEMBLIES

What is a reaction wheel assembly?

A reaction wheel is a type of flywheel used primarily to control the attitude of a spacecraft of satellite. They work using electric motors, which spin the wheels to tilt or point a spacecraft using momentum. Essentially, they keep a spacecraft still, making them a good option for communications satellites that point at fixed targets on the ground.

The HR04, HC7 and HC9 reaction wheel assemblies have been designed to offer extreme flexibility in packaging options as well as providing precision performance supported by advanced drive technology, in a greatly reduced package.

Reliability does not need to be compromised for a small scale RWA response in a large market demand.
