Problems solved by technology

But at present, all portable Ku-band satellite communication antennas can only be used statically on the ground, and do not have the function of tracking satellites with the movement of the antenna carrier
In particular, the portable Ku-band satellite communication antenna system is applied on the sea, and there are no reports and applications for products that track and align satellites when the hull is bumping with the waves.

Abstract

The invention brings forward a portable Ku-waveband marine satcom-on-the-move satellite communication antenna system comprising a portable Ku-waveband satellite communication antenna and a portable orientation / rolling rotary table; and an antenna control board and a rotary table control board respectively control the portable Ku-waveband satellite communication antenna and the portable orientation / rolling rotary table. The antenna control board calculates orientation / pitching / rolling angular-rate sensor signals and a satellite beacon receiver signal of the portable Ku-waveband satellite communication antenna so as to form an angular speed of the portable satellite antenna with movement of the orientation / rolling rotary table and satellite beacon receiver signal closed-loop tracking; and the rotary table control board calculates orientation / rolling angular-rate sensor signals at the orientation / rolling rotary table and reads an MEMS inertial navigation rolling angle signal sampled by the antenna control board so as to form the angular speed of the orientation / rolling rotary table with wave bumping and rolling angle position closed-loop tacking, so that the satellite antenna is always in a state of being aligned at the satellite. According to the invention, the application of the portable Ku-waveband satellite communication antenna is extended to the marine field and the system can be carried conveniently.

Description

technical field [0001] The invention belongs to the technical field of satellite communication antennas, and in particular relates to a portable Ku-band satellite communication antenna system in motion at sea. Background technique [0002] The application technology of the portable Ku-band satellite communication antenna system on land is mature, and there are many related products. But at present, all portable Ku-band satellite communication antennas can only be used statically on the ground, and do not have the function of tracking satellites with the movement of the antenna carrier. Especially the portable Ku-band satellite communication antenna system is applied on the sea, and the product of tracking and aligning the satellite under the bumpy state of the hull with the waves has not yet been reported and applied. Contents of the invention [0003] The technical problem solved by the present invention is to provide a portable Ku-band satellite communication antenna sy...
