Abstract
An antenna controller mounted on a movable body is provided for controlling antenna driving for satellite tracking. The antenna controller comprises a step tracking circuit for performing step tracking operation on a turning face of the movable body while receiving electromagnetic waves from a satellite, and for calculating an antenna pointing direction in which an intensity of the electric wave is strongest. An antenna driving circuit drives the antenna in the antenna pointing direction, while a reference output correcting circuit adds a correction quantity to a reference output of a rate sensor based on a result of the step tracking operation.
