アンテナ自動追尾システム。 A main antenna, a sub-antenna with a larger beam width than the main antenna, and a phase-synchronized tracking receiver.
In the automatic antenna tracking system, the antenna automatic tracking system includes a route switch that switches signals from the main and auxiliary antennas and sends the signals to the phase-synchronized tracking receiver, and a condition determiner that controls the route switch. includes the main antenna route and the sub antenna route as well as the combination route of the main antenna and the sub antenna in the switching route, and the condition determiner sets the combination route of the main antenna and the sub antenna when the phase locked loop is in an asynchronous state. An automatic antenna tracking system characterized by controlling the route switching device so as to control the route switching device.
