Summary
BRASILSAT 1 was a communication satellite launched by EMBR on February 8, 1985, from Guiana Space Centre using an Ariane 3 launch vehicle. The spacecraft had dimensions of 7.1 meters in length and 2.2 meters in diameter, with a dry mass of 541 kg and a launch mass of 637 kg. It was equipped with 24 C-band transponders (with the capability to add 6 more) for communication purposes. The satellite's power supply came from solar cells and batteries. Its design lifetime was 8 years, but it operated successfully for 17 years. BRASILSAT 1 was manufactured by HSES and utilized a TE-M-700-5 motor with a body-mounted shape.
