Intelsat K (later termed Satcom K4 and NSS-K) was a geostationary communication satellite built by Lockheed Martin. It was located at orbital position of 21.5 degrees west longitude and was owned by SES World Skies. The satellite was based on the AS-5000 platform and its life expectancy was 10 years. It was retired from service in August 2002 and transferred to a graveyard orbit.
The satellite was purchased from Intelsat by New Skies and renamed to NSS-K. It is also the former Satcom K4 of GE Americom.
