| 摘要 |
A method for two way communication between a first station and a second station each said station comprising receiving means and transmitting means for receiving and transmitting electromagnetic communication signals, whereby one or more signals are transmitted from the first station to the second station, and the direction of the physical boresight axis of the antenna of the first station is controlled, said controlling comprising electrically changing or switching the direction of optimum reception or electric boresight of reception of the antenna of the first station in one or more directions displaced from the direction of the physical boresight axis by changing electric characteristics of said feeding means, monitoring, during said switching of the direction of optimum reception or electric boresight of reception, one or more signals carrying information representing variations in receiving signal strength of one or more signals transmitted from the second station and received by the first station during said switching, and mechanically moving the antenna in response to the results of said monitoring of the signal strength information signal(s) thereby changing the direction of the physical boresight axis so as to reduce or minimize pointing errors of the antenna in relation to the second station and increase or maximize the strength of signals received by the first station from the second station and/or vice versa.
