Stationed at 65 deg W. Brazilsat 1 & 2 provide telecommunications services to Brazil. Canada's Spar Aerospace was awarded a $125 million contract to build, under license, two satellites based on Hughes' HS-376 design (similar to Anik D). Brazilsat 1 & 2 were the first two elements of Brazil's national Sistema Barasilero de Telecommunicacoes por Satelite (SBTS) network. Spacecraft: Based on Hughes HS-376, single antenna on despun platform, spin stabilised, hydrazine thrusters, body mounted solar cells provide 982 W BOL. Payload: 24 C-band transponders with 6 spares, 10 W TWTA, EIRP >34 dBW over most of Brazilian territory
Financial/Operational:
Contract issued in 1990 for 2 units HS-376W. B1-B2 have dedicated transponders for government use. Positioned in geosynchronous orbit at 65 deg W in 1985-1994; 63 deg W in 1994-1996; 79 deg W in 1996-1998; 144 deg W in 1998-1999 As of 5 September 2001 located at 143.96 deg W drifting at 0.005 deg E per day. As of 2007 Mar 9 located at 145.69E drifting at 2.591W degrees per day.

Stationed at 105 deg W. Brazilsat 1 & 2 provide telecommunications services to Brazil. Canada's Spar Aerospace was awarded a $125 million contract to build, under license, two satellites based on Hughes' HS-376 design (similar to Anik D).

Contract issued in 1990 for 2 units HS-376W. B1-B2 have dedicated transponders for government use. Positioned in geosynchronous orbit at 70 deg W in 1986-1995; 92 deg W in 1995-1999 As of 4 September 2001 located at 62.91 deg W drifting at 0.007 deg W per day. As of 2007 Mar 7 located at 32.58W drifting at 2.263W degrees per day.

28 C-band transponders, 1 X-band transponder (military). Stationed at 70.05 deg W. Positioned in geosynchronous orbit at 70 deg W in 1994-1999 As of 3 September 2001 located at 70.00 deg W drifting at 0.003 deg W per day. As of 2007 Mar 11 located at 71.44W drifting at 0.304W degrees per day.

Brazil's SCD-2 satellite was aboard Orbital Science's L-1011 Stargazer aircraft when it took off from the Cape Canaveral Air Station's Skid Strip (Runway 02/20, 28.2N 80.6W) at 23:05 GMT on Oct 22 and flew to the drop zone near Cape Canaveral (in the Mayport, Florida, Warning Area) at 29.0N 78.3W. The Pegasus ignited 5 seconds after drop. The first stage carried a NASA experiment attached to its right wing, to study hypersonic boundary layer separation. The 115 kg Satelite de Coleta de Dados (Data Collection Satellite) relays data from environmental monitoring stations. Air dropped in Mayport DZ.

Brasilsat B4 was a C-band geosynchronous communications satellite, replacing the 15-year-old Brasilsat A2 for the Brazilian communications company Embratel. Positioned in geosynchronous orbit at 75 deg W in 2000. As of 2 September 2001 located at 92.03 deg W drifting at 0.011 deg W per day. As of 2007 Mar 9 located at 70.08W drifting at 0.020W degrees per day.

Launch was due on August 25. Was to have been on third qualification flight after two previous failures. The launch had already been delayed from October 2002, then May 7 and June 20 2003. It appeared that one of the strapon boosters ignited by accident. The two satellite payloads were also destroyed in the blast, as was the launch pad.

Initially planned for launch on Delta 4M+ (4,2). Launch delayed from January 10. Placed in geosynchronous orbit but reports indicated there were problems deploying one of the solar panels. As of 2007 Mar 11 located at 63.07W drifting at 0.006W degrees per day.

Unguided test launch. During the 45 seconds total burn time of both motors the vehicle was accelerated to a final velocity of 1676 m/s. The payload segment with an approximate weight of 400 kg was carried to an apogee height of almost 240 km, which was reached 252 seconds after lift-off. At T+650 seconds the payload landed 190 km northeast of the launch site in the ocean, only 700 meters from the nominal impact point.

Third China-Brazil joint earth resources satellite. Much higher resolution optics and multispectral sensors expected to be useful for some military applications as well. The satellite raised its orbit to its operational altitude of 773 km two days after launch.
