Project abstract
The project consists of an advanced satellite-based telecommunication system which works at frequencies beyond 20 GHz , namely in frequency bands very sensitive to the electromagnetic propagation impairments due to tropospheric phenomena such as rain, clouds etc. The system is based on the basic principle of the adaptivity according to which the limited power available on-board is radiated in a selective manner by routing most of it preferably towards directions where the adverse atmospheric conditions produce greater attenuation.
The project is very defying considering the need of advanced technologies and the joint exploitation of real-time data coming from the meteorological observation. The system is expected to find application in the frame of the multimedia telecommunications of the future and of the direct TV transmission from satellite. The project is completed.
