Intelsat 901 (IS-901) was the first of 9 new Intelsat satellites launched in June 2001 at 342°E, providing Ku-band spot beam coverage for Europe, as well as C-band coverage for the Atlantic Ocean region, and provides features such as selectable split uplink for SNG, tailored for increased communications demands such as DTH and Internet.
On 9 October 2015, Spacenews.com reported that in April 2015, the Russian satellite Olymp-K had moved to within 10 kilometres (6.2 mi) of Intelsat 901 and the nearby Intelsat 7, causing concerns of a safety-of-flight incident. Attempts by Intelsat to contact the Russian satellite's operators were not successful, and no reason for the satellite's movement was given by the Russian government. The move sparked classified meetings within the Department of Defense and heightened suspicions that that Olymp-K satellite was performing signals intelligence, or was possibly an anti-satellite weapon.
