Problems solved by technology
Its alignment accuracy is limited by the accuracy of the position information detection mechanism and the response speed and precision of the servo mechanism, so it is difficult to obtain ideal results, and after the antenna carrier passes through tunnels, culverts and other signal blind areas, it needs to re-align the satellite, although the signal recovery time is limited. The length is different, but they all prolong the communication signal interruption time

The invention discloses a liquid suspension type antenna frame and a Satcom on the Move (SOTM) antenna automatic tracking platform. The liquid suspension type antenna frame comprises a spherical liquid container, wherein the lower part of the spherical liquid container is filled with mercury; a suspension seat is suspended on the mercury; a connecting platform is arranged on the upper surface of the suspension seat and used for being connected with an antenna; a seal ring is arranged between the top end of the suspension seat and the spherical liquid container, and is used for sealing the mercury; the upper surface of the seal ring is in contact with a retaining ring; an adjusting device is fixed in the suspension seat and used for adjusting the balance of the suspension seat suspended in the spherical liquid container; a balance weight is arranged on the adjusting device. The liquid suspension type antenna frame and the SOTM antenna automatic platform provided by the invention have the advantages that during the movements of a carrier, the elevation angle of the antenna can automatically maintain the optimum angle which is determined in the static state of the carrier without the help of any detection device or electric control; the azimuth angle of the antenna can achieve real-time automatic tracking along with the movements of the carrier, so as to maintain an original angle.
Description
technical field [0001] The invention relates to a liquid-suspension antenna frame and a self-tracking platform for communication antennas in motion. Background technique [0002] The satellite ground station communication system on the move, abbreviated as "Sat-com on the move" in English, commonly known as the communication in motion, is a new product that has appeared in recent years. Mobile communication provides a new communication mode, which is different from "quiet communication", which can be loaded on vehicles, ships and other vehicles to provide satellite communication services for moving vehicles. Through the "communication in motion" system, moving carriers such as vehicles, ships, and airplanes can track satellites and other platforms in real time during the movement process, and continuously transmit multimedia information such as voice, data, and images, which can meet various military and civilian emergency communications and communication requirements. The ...
