Gyro stabilized platform for scanning antenna

摘要

An antenna apparatus comprising a gimbals with two axes crossing at right angles mounted on a fixed stand, an antenna base attached to said gimbals to be rocked with the rotation of said gimbals and holding an antenna, flywheels attached to said antenna base for stabilizing said antenna base applying the principle of precession of gyro, a first driving mechanism for rocking said antenna in the elevational direction, a second driving mechanism for rocking said antenna in the azimuthal direction, and a third driving mechanism for shifting the center of gravity on said gimbals in a direction across the direction of rotation of said first driving mechanism.
