Abstract

The invention relates to a portable narrow band satellite communication device. The portable narrow band satellite communication device comprises an indoor unit (IDU) and an outdoor unit (ODU), wherein the IDU comprises an IDU small terminal, a video encoder, a user operation panel, a satellite searching device, a voice access gateway, a power splitter and a power supply system, and the ODU comprises a low-noise block downconverter (LNB), a block-up converter (BUC), connecting cables, a duplexer antenna and an image acquisition device. Further, a tablet personal computer (PC) is arranged, thetablet PC is connected with a back-bearing case through a network interface (RJ45), and therefore audio transmission and video transmission are achieved. The portable narrow band satellite communication device has the advantages of being compact in structure, convenient to carry, easy to operate, fast in deployment, little in communication jamming, good in confidentiality and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to a portable narrowband satellite communication device and a control method thereof. Background technique [0002] When a public emergency occurs, the scene of the emergency generally does not have communication capabilities, or there are problems such as communication congestion on the public network, which seriously affects the speed of rescue work and increases the loss of the accident. In order to ensure that the relevant functional departments can respond quickly, make correct decisions and deal with them accurately, and effectively reduce the losses and injuries caused by the incident, it is necessary to fully understand the situation at the scene of the incident in an all-round way, and communicate fully with the on-site headquarters in real time, so as to benefit the emergency command center Organize and mobilize appropriate resources, take effective measures to reduce acc...
