Brasilsat B1

From Wikipedia, the free encyclopedia

The satellite Brasilsat B1 was launced on August 10, 1994, by an Ariane (rocket) Rocket model 44L at the launching base in Kourou in French Guiana.

It was constructed between the US and Brasil and is classified as a second generation satellite. It is a large size and more powerful than the previous generations of satellites.

The Boeing Company contracted the acquisition of three satellites from, in this case, Hughes Electronics Corporation. As part of the contract, Hughes would divide the work with the firm Promon Engenharia SA of São Paulo. The Institute of Space Research (Brazil) - INPE of São José dos Campos of Brazil, was the location of satellite tests Brazilsat B1 and B2. The satellites B3 and B4 were tested in the Hughes laboratories.

The contract also included renovation of sensor equipment and telemetry of Guaratiba Center for Satellite Signaling (Brazil), located in Rio de Janeiro (state), besides the automation and installation of security equipment in the Tanguá Control Station (Brazil).

In March 2007, Brasilsat B1 was moved from its former orbital position and replaced by Brasilsat B4.

On June 2nd 2008, Brasilsat B4 was also moved from that orbital position and replaced by Star One C2, now placed at 70,0º W.
