The Brasilsat B1 satellite is a powerful communications satellite that was launched in 1996. It was built by Hughes Space and Communications Company.
The Brasilsat B1 satellite is a geostationary satellite, which means it orbits the Earth at an altitude of approximately 36,000 kilometers. This allows it to provide coverage for a large portion of the Americas.
The satellite has a mass of approximately 3,600 kilograms.

General Information
Brasilsat B1 was launched on August 10, 1994. The satellite was launched from Arianespace using an Ariane 44 LP vehicle.
It was originally positioned at 70.0° W, but is now inactive and located at 68.0° W.
Brasilsat B1 is designed to cover Brazil.
Here are the details of the satellite's transponders and frequencies:
The satellite's planned life was 12 years.
C Band Details
The C Band Details of Brasilsat B1 are quite impressive. The satellite has 28 main transponders, which is a significant number for a communications satellite.

These transponders are backed up by additional units, but unfortunately, we don't have the exact number in the provided data. The power output is substantial, with 24 transponders capable of 13 W each and 4 transponders capable of 15.5 W each.
The bandwidth of the C Band is divided among these transponders, with 27 of them having a bandwidth of 36 MHz each, and one having a bandwidth of 33 MHz (1AE). This level of bandwidth is crucial for transmitting large amounts of data.
The coverage area of the C Band is limited to Brasil, which is a significant constraint for a communications satellite. The EIRP (Effective Isotropic Radiated Power) max is 38 dBW, which is a measure of the maximum power that can be transmitted by the satellite.
The G/T (Gain-to-Noise-Temperature) max is -2.5 dB/K, which is a measure of the satellite's sensitivity to noise. The polarization of the C Band is linear, with the option to switch between horizontal and vertical polarization.

Technical Specifications
The Brasilsat B1 satellite has a launch mass of 2,100 kg and a dry mass of 1,200 kg. This is a significant difference, highlighting the amount of fuel required for its operation.
It was launched on October 13, 1996, aboard an Ariane 4 rocket. This marked the beginning of its mission to provide telecommunications services to Brazil.
The satellite operates in geostationary orbit at a location of 55° W longitude. This position allows it to cover a significant portion of the Americas.
Its design life is 15 years, with a power output of 2.5 kW. This ensures a stable and reliable operation throughout its lifespan.
The Brasilsat B1 satellite has a payload capacity of 25 transponders. This allows it to support a wide range of telecommunications services.
