Reaction wheels are a class of electrical actuators for satellites that do not require any propellant and are capable of providing torques on satellites. Seringkali menembakan gas hydrazine (H2Z) agar rotasi satelit agar satelit stabil di orbit, satelit perlu beberapa kali di kalibrasi agar tetap pada orbitnya.
