History

It was constructed by the United States and Brazil and is classified as a second generation satellite. It is larger and more powerful than the previous generation of satellites.

The Boeing Company contracted the acquisition of three satellites from Hughes Electronics Corporation. As part of the contract, Hughes would divide the work with Promon Engenharia SA of São Paulo. Brasilsat B1 and B2 were tested by the Institute of Space Research - INPE of São José dos Campos, Brasilsat B3 and B4 were tested in the Hughes laboratories.

The contract also included renovation of sensor equipment and telemetry, provided by Guaratiba Center for Satellite Signaling, located in Rio de Janeiro, as well as automation and installation of security equipment in the Tanguá Control Station.

Current status

In March 2007, Brasilsat B1 was moved from its former orbital position at 70.0°W to 68.0°W and replaced by Brasilsat B4. On June 2, 2008 Brasilsat B4 was moved from its new position to 84.0°W and replaced at 70.0°W by Star One C2. Brasilsat B3 is currently at 75.0°W.

Of the four Brasilsat satellites, only B3 and B4 are currently transmitting signals.
