A “Europeanized” Soyuz rocket will launch from the Guiana Space Center with the third set of O3b satellites joining a constellation of telecommunications satellites placed into an 8,063-Kilometer orbit above the equator to deliver low-latency data services to the developing world. O3b stands for “the other three billion” in reference to the world’s population that can not connect to the Internet through conventional means; it is operated by O3b Networks, a wholly owned subsidiary of SES S.A. Outfitted with a Fregat upper stage, Soyuz will directly deliver the four 700-Kilogram satellites into their checkout orbit over the equator.
