Intelsat 804 was a communications satellite operated by Intelsat. Launched in 1997 it was operated in geostationary orbit at a longitude of 44 degrees east for around 8 years.
Satellite
The fourth of six Intelsat VIII satellites to be launched, Intelsat 804 was built by Lockheed Martin. It was a 3412 kg spacecraft. The satellite carried a 2xLEROS-1B apogee motor for propulsion and was equipped with 38 C Band transponders and 6 Ku band transponders, powered by 2 solar cells more batteries.[3] It was designed for a fourteen-year service life.[4]
