Example Embodiment

[0043] To realize the function of receiving and transmitting marine communication signals on the shipborne satellite communication antenna, first, the radome itself should have good wave permeability, and can withstand the harsh external environment to protect the system; secondly, the antenna needs to rotate 360° Infinite position, pitch 0-110° rotation, polarization ±90° rotation, so as to ensure that the antenna is always aligned with the selected communication satellite under the condition of the carrier's attitude and heading changes, realizing the satellite communication function.

[0044] The technical scheme of the present invention will be further described in detail below in conjunction with specific embodiments and drawings:

[0045] Such as figure 1 As shown, the shipborne satellite communication antenna includes: a radome part 1, an azimuth transmission part 2, a pitch transmission part 3 and a polarization transmission part 4. The radome part 1 and the azimuth transmi...

Abstract

The invention discloses a shipborne satellite communication antenna. The antenna comprises a radome portion, an orientation transmission portion, a pitching transmission portion and a polarization transmission portion. The radome portion and the orientation transmission portion are connected and fixed through a pedestal. The orientation transmission portion and the pitching transmission portion are connected through an orientation rotation platform. The pitching transmission portion and the polarization transmission portion are connected and fixed through an antenna surface supporting plate and a rectangular bend waveguide 2. The structure of the radome portion is designed reasonably, sealing performance is good, an internal system of the antenna can be effectively protected and the antenna is suitable for an offshore poor working condition. The structures of the orientation transmission portion, the pitching transmission portion and the polarization transmission portion of the shipborne satellite communication antenna are designed compactly, operation is stable and reliable, the three portions can be rotated independently and can be rotated simultaneously, real-time tracking and automatic satellite aiming functions can be well realized and a smooth space communication link between a boat and a satellite is guaranteed.

Description

Technical field [0001] The invention relates to a marine satellite communication antenna device, which belongs to the technical field of satellite communication. Background technique [0002] The marine environment is extremely complex. Two-thirds of the earth’s surface is covered by sea water. With the rapid development of modern mobile communication systems, marine operations and marine transportation crews and national maritime security guards have a good understanding of national current affairs and market trends. There is an urgent need for information, which makes maritime communications particularly important. The satellite communication system solves the problem that when the hull's attitude and heading change continuously, the satellite antenna beam always points to the communication satellite 36,000 kilometers away from the earth, and can receive and send files, voice, video, image, and fax in real time without interruption. Various data and information have realized m...
