despun antenna

Despun antennas are directional antennas with a narrow radiation pattern. They are used in satellite communications and always direct their sharply focused beam to the same hotspot on the earth. Regardless of the satellite's rotation, Despun antennas are readjusted so that their footprint always illuminates the same geographical area on the earth's surface.
