Brasilsat B2 is a Brazilian communications satellite launched on March 28, 1995, by an Ariane rocket model 44L at Kourou in French Guiana.[2]


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 January 2008, Brasilsat B2 was moved from its former orbital position at 65.0°W to 92.0°W. Brasilsat B2 is now in inclined orbit at 63º W.

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