Embodiment Construction

[0068] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0069] The invention provides an S-band satellite communication terminal, which can provide high-speed long-distance real-time communication service covering the sea area, and data is input through a network interface; it is connected to a relay satellite network through a parabolic antenna.

[0070] Such as figure 1 and figure 2 As shown, the satellite communication terminal mainly includes a radome, a parabolic antenna 5, a servo tracking device 3, an S-band satellite relay communicator 6 and a temperature control unit.

[0071] Among them, the parabolic antenna 5, the servo tracking module 3, the S-band relay communication device 6 and the radome 12 are respectively designed for weight reduction. The lower the center of gravity of the buoy and the farther it is from the center of buoyancy, the less affected the buoy platform is by wind...

Abstract

The invention discloses an S-band satellite communication terminal for an offshore mobile platform. The S-band satellite communication terminal comprises a parabolic antenna, a servo tracking device and an S-band satellite relay communication machine, the parabolic antenna is located at the top of the servo tracking module, and the parabolic antenna and the servo tracking module are electrically connected to the S-band satellite relay communication machine; the parabolic antenna is used for receiving a satellite forward electric wave signal and radiating a backward electric wave signal to thespace; the servo tracking device is used for calculating the pointing directions of the platform and the satellite, correcting the pointing directions by utilizing the received signal strength value,and controlling the parabolic antenna to point to the satellite according to the corrected pointing directions; the S-band satellite relay communication machine is used for realizing two-way communication between the terminal and the relay satellite and outputting shore-based instruction information to the offshore mobile platform; and performing feedback of the received signal intensity value tothe servo tracking device in real time. The satellite communication terminal is small in size, weight and power consumption, and meets the application requirements of offshore buoys with the diameteras small as 1 m.

Description

technical field [0001] The invention relates to the field of maritime satellite communication, in particular to an S-band satellite communication terminal used for a mobile platform at sea. Background technique [0002] Marine technology is an important support for the national marine strategy, and marine monitoring technology is the basis for marine development, control, and comprehensive management. With the continuous development and maturity of technologies such as satellite communication, satellite remote sensing, underwater acoustic telemetry and sensors, marine monitoring has entered the era of three-dimensional monitoring of the marine environment from space, along the coast, on the water surface and underwater. There are many types of marine monitoring platforms, such as active, passive and towed monitoring platforms. As a widely used passive monitoring platform, marine buoys have the characteristics of all-weather, long-term continuous and fixed-point monitoring, ...
