Proposal of a satellite system for emergency situations

摘要

In emergency situations or in the case of disasters (cyclone, flood...), there is a vital need for communications services such as voice, video or useful data (logistical, medical data, support for stricken population...) in order to assist populations. Satellite links seem to be a cost effective way to ensure secure and high data rate communications in these situations where users are scattered all over the area. This article deals with the setting up of such a satellite communication system that would operate in Ka-band. Estimating the frequency reuse factor, a first analysis of the system's performance is proposed.
