Problems solved by technology

[0008] In order to overcome the prior art when satellite phone terminals are used for telephone communication, satellite phone terminals based entirely on the Inmarsat core board and satellite phone terminals that use the Inmarsat core board for self-management and peripheral application integration design can only be used outdoors. The technical problem that can no longer be used in the working cabin, the present invention provides the main board of the external unit of the dual-mode satellite telephone terminal

Abstract

The invention discloses a dual-mode satellite telephone terminal extravehicular unit main board which comprises a CPU processor, an Ethernet unit with a network transformer, a USB controller and an audio unit. The Ethernet unit, the USB controller and the audio unit are connected with the CPU processor. The audio unit is connected with the USB controller. The USB controller is used for communicating with an Inmarsat core board. Through the USB controller, configuration program upgrading can be carried out on the CPU processor. Through the dual-mode satellite telephone terminal extravehicular unit main board, a satellite telephone terminal realizes the work modes of extravehicular receiving and cabin processing.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a main board of an outboard unit of a dual-mode satellite telephone terminal. Background technique [0002] The mobile communication system based on base stations and antennas has a very limited range of use, and it cannot provide communication services for maritime ships, aircraft, offshore operating platforms, field exploration and mining, and unattended stations without base stations. When a large natural disaster occurs, the base stations or antennas in the disaster area are damaged, causing the mobile communication network to be paralyzed and unable to provide communication services for disaster relief. [0003] For the above situation, communication services can only be provided through the Inmarsat communication system (International Maritime Satellite Communication System). The Inmarsat communication system is mainly connected through the maritime satelli...
