Zusammenfassung:A reflector deployment and pointing mechanism (10), for deploying and pointing a reflector (12) of an antenna movably mounted on a structure (14), has a first actuator (20) mounted on the structure (14), a second actuator (30) mounted on the first actuator (20), and a third actuator (40) mounted on the second actuator (30) and connected to the reflector (12). The first (20) or second actuator (30) is the deployment actuator, and, respectively, the second (30) or first (20), and the third (40) actuators are the pointing actuators and have their axis of rotation (36 or 26, 46) generally intersecting a feed oriented point (13) of a signal reflecting surface (16) of the reflector (12).
