About this launch
Launched in 1996-8, the Inmarsat-3s were built by Lockheed Martin Astro Space (now Lockheed Martin Missiles & Space) of the USA, responsible for the basic spacecraft, and the European Matra Marconi Space (now Astrium), which developed the communications payload. Brazil's second generation of communications satellites are the result of joint engineering and manufacturing efforts in the United States and Brazil. The new spacecraft are called the Brasilsat B series, and are widebody, more powerful versions of Hughes Space and Communications Company's popular HS-376 model. EMBRATEL, Brazil's telecommunications company, signed a contract in August 1990 for two spacecraft. In December 1995, with those new satellites in orbit and rapidly filling with customers, EMBRATEL exercised an option for a third spacecraft. A fourth was ordered in June 1998.
