Abstract

This study inserts itself within the framework of the first phase of a post-disaster emergency situation. The purpose here is to propose and study a solution allowing to establish very quickly a minimal low bit rate satellite link in Ku/Ka or Q/V band, while using the available resources of the satellite, a single-user ground terminal with a low transmission power, a small diameter antenna, and a dedicated Tx/Rx system, characterized by an electric consumption which shall be as low as possible (battery or solar panels). The transmission channel is modeled within the Juzzle open source environment software, with an adaptive strategy based on the DVB-S2 adaptive modulation and coding (ACM) scheme.
