Problems solved by technology

[0003] 1. Its base stations are basically built in relatively densely populated areas. In areas with sparse business, remote areas, islands, and mountains, it is often impossible to build stations for various reasons. That is to say, in such areas, the existing The terrestrial cellular mobile communication system cannot complete its mobile communication services
[0004] 2. Due to the limitations of existing mobile communication system resources and technologies, it is impossible to provide large data volume and high-speed communication services such as images and videos
[0005] 3. In disaster situations, the existing ground communication network is often easily destroyed and difficult to recover quickly
[0007] However, the usual satellite communication earth station is a complex set of communication equipment, which is bulky, difficult to carry, and especially complicated to operate. Under emergency application conditions, embarrassing events that must be evacuated from the site often occur before the communication service is opened.
Or, it must be set up and opened on site in advance, so that it loses its significance as an emergency communication device

Abstract

The invention relates to an intelligent portable planet communication earth station, formed by antenna box and terminal box, wherein it comprises antenna reflective face, feedback source, polarity adjuster, direction / incline adjuster, antenna controller, L-frequency planet mark track receiver, GPS receiver, planet communication modulator / demodulator, signal coder / decoder. The antenna controller via incline device and GPS receiver confirms the initial incline angle of antenna position and antenna reflective face; the polarity adjuster matches the polar angle of antenna and the planet transmitter; the modulator / demodulator and signal coder / decoder transmit the planet mark signal output via track receiver to transmit communication signal. The invention can support voice, data, video signals, etc, with low weight and small volume.

Description

Technical field: [0001] The invention relates to a satellite communication system device and a control method for controlling the system, in particular to a portable ultra-small-aperture satellite communication earth station carried on the back and a control method thereof. Background technique: [0002] The existing terrestrial cellular mobile communication system shows the following deficiencies in terms of its business types and coverage: [0003] 1. Its base stations are basically built in relatively densely populated areas. In areas with few services, remote areas, islands, and mountains, it is often impossible to build stations due to various reasons. That is to say, in such areas, the existing The terrestrial cellular mobile communication system cannot complete its mobile communication services. [0004] 2. Due to the limitations of existing mobile communication system resources and technologies, it is impossible to provide large data volume and high-speed communicat...
