It was also the first to use experimentally with some success electric propulsion in geostationary orbit.
Embratel, a formerly state-controlled communications company in charge of the Brazilian Satellite Communication System (Sistema Brasileiro de Comunicação por Satélites--SBTS), owns and operates a series of satellites that are positioned in geostationary orbit over the equator.
Many variants have been proposed, but the concept most often refers to an elevator that reaches from the surface of the Earth to geostationary outer space, with a counterweight attached at its outer end.
A FGB ("Functional Cargo Block") engine section originally built as a cancelled Mir module was incorporated into the upper stage used to inject the payload into orbit, similarly to modern geostationary satellites providing apogee impulse themselves, since the planned "Buran-T" upper stage had not yet progressed beyond the planning stage.
The Geostationary Earth Radiation Budget (GERB) is an instrument aboard EUMETSAT's Meteosat Second Generation geostationary satellites designed to make accurate measurements of the Earth Radiation Budget.
Plesetsk is not ideally suited for low inclination or geostationary launches because of its high latitude of 62 degrees north (as compared to the Guiana Space Centre at 5° north or the Kennedy Space Center at around 28° north).
C5 was designed for Inter-Continental traffic where many transmission paths were lengthy terrestrial, often submarine cable, and geostationary satellite links.
