Why I like this video? Because it includes closeup shots from electronic and mechanical engineering heaven! Designed and built by Astrium and the European Space Agency, Alphasat is the most sophisticated commercial communications satellite ever built. Alphasat carries a new generation of advanced geomobile communications payload in L-band, will enable communications across Europe, Asia, Africa and the Middle East with increased capacity. On top of those, it features eight new-generation digital signal processors for the payload, and an 11-metre antenna reflector. Pretty amazing right?
