Abstract
A hybrid geostationary and low earth orbit (LEO) ground station antenna provides a geostationary receive antenna (,) which generates a narrow receive antenna beam for use with geostationary satellites. The ground station antenna can be either manually positioned so that the normal boresight of the antenna is directed toward the geostationary satellite serving the subscriber, or may be positioned using a cradle (,) which provides motion in the pitch, roll, and yaw axes. The ground station antenna also includes a LEO receive antenna (,) and a LEO transmit antenna (,) which receive which communicate with LEO satellites by way of wider beam, lower gain antenna beams. The geostationary receive antenna (,) is used in conjunction with the LEO satellites and during operations which involve communication with both types of satellites.
