A rare and historically coherent ensemble of 7 original technical documents in the form of offprints, published between 1980 and 1988. These working papers come directly from the professional archives of a high-level aerospace engineer. At this pivotal time, the space industry was tipping from a purely government-driven era toward privatized launches and the rise of mobile telecommunications (Ku band, Ka band, constellations). This lot constitutes a true time capsule of the transatlantic technological elite at the end of the Cold War, bringing together the major American manufacturers and the European Space Agency (ESA).
