NSS-5 (Formerly known as Intelsat 803 and NSS-803) is a communications satellite operated by Intelsat and after by SES World Skies. Launched in 1997 it was operated in geostationary orbit at a longitude of 50.5 degrees east for around 14 years.
Satellite
The third of six Intelsat VIII satellites to be launched, NSS-5 was built by Lockheed Martin. It was a {{convert|3412|kg|lb|adj=on}} spacecraft. The satellite carried a double LEROS-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. It was designed for a fourteen-year service life.{{cite web|url=http://space.skyrocket.de/doc_sdat/intelsat-8.htm|title=Intelsat-8 (801, 802, 803, 804) / NSS 803 → NSS 5|first=Gunter|last=Krebs|work=Gunter's Space Page|access-date=May 5, 2017}}
Launch
The launch of NSS-5 made use of an Ariane 4 rocket flying from Guiana Space Centre, Kourou, French Guiana. The launch took place at 23:58 UTC on September 23, 1997, with the spacecraft entering a geosynchronous transfer orbit. NSS-5 subsequently fired its apogee motor to achieve geostationary orbit.
