Embodiment Construction
[0021] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0022] to combine figure 2 , the four-axis structure antenna stabilization frame is composed of a frame part and a control chassis part. The frame part can be divided into base, azimuth control frame (outer frame) 4, pitch control frame (middle frame) 2, and roll control frame (inner frame) 7 parts. motor and position detector. The orientation control frame is installed on the base, and the driving motor 10 and the angle detector 11 of the orientation control frame are installed inside the base. The azimuth control frame is U-shaped, and the pitch control shaft is installed on the azimuth control frame. Angle detector8. The pitch control frame is a closed O-shaped frame. It is defined that the initial position of the pitch control frame is when the two frame planes of the pitch control frame and the azimuth control frame coincide, and the initial pitch angle ...

The invention relates to a four-shaft stable framework for an antenna and a control method. The stable framework comprises a framework part and a control case, wherein the framework part comprises a base, an azimuthal control frame, a pitching control frame and a rolling control frame; and control motors and detectors are respectively mounted on the base and each frame. Under the condition that the posture of a carrier is unknown, the posture of an antenna under a geographic coordinate system can be detected and is compared with the calculated posture of an antenna system under the geographic coordinate system to obtain a posture difference value; and the difference value is compensated by using a framework system to stabilize the antenna. With the globalization characteristics of ship navigation, the invention provides the four-shaft stable framework, which meets the global heading requirement and is more conductive to tracking objects in an all-day range.
Description
technical field [0001] The invention relates to a ship satellite antenna stabilization system, and also relates to a control method of the ship satellite antenna stabilization system. Background technique [0002] In recent years, with the development of information technology, the mobile carrier's demand for information communication has increased significantly, resulting in the related products of mobile carrier satellite communication. To meet the needs of global navigation, the existing two-axis frame antenna stabilization system cannot meet the requirements for use in ships.
