Intelsat-11 (IS-11, PAS-11) at 43° West
|Launch vehicle:||Ariane 5G|
|Expected lifetime:||15 Years|
In April 2005 satellite operator PanAmSat ordered the PAS-11 satellite with Orbital Sciences. Inc. (Orbital ATK – Northrop Grumman). PanAmSat’s new spacecraft will provide C- and Ku-band fixed telecommunications and direct-to-home television broadcasting services from a mid-Atlantic orbital location. The new satellite is the fourth one PanAmSat has purchased from Orbital since 2001 and is based on the company’s Star 2-platform. PanAmSat previously purchased three C-band satellites for U.S. domestic communications services from Orbital. The satellite would serve the Americas market and was to replace Intelsat-3R which became at the end of its design life.
The satellite was designed for 15 years of service, PAS-11 will carry 18 active Ku-band and 16 active C-band transponders. The satellite will generate approximately 4.5kW of electrical power and will weigh approximately 2,500kgs at launch. Delivery of the satellite was scheduled in the first quarter of 2007. The contract included options for two additional spacecraft, each of which would generate approximately 4.7kW of power and would be delivered about 24 months after exercise of the contract options.
In early 2006 PanAmSat ordered long lead items for a back-up satellite for PAS-11, which was called PAS-11R. In May 2007, after the acquisition of PanAmSat, satellite operator Intelsat confirmed the contract for the satellite to be completed in 2008. PAS- 11R was renamed Intelsat-16.
In February 2007 satellite operator Intelsat acquired PanAmSat and all PanAmSat satellite assets were transferred to Intelsat. PAS-11 was renamed of the satellite to Intelsat-11 (IS 11).
The satellite was booked as the payload on the maiden Land Launch Zenit-3SLB launch, but was rebooked in March 2007 on an Ariane launch vehicle. Intelsat-11 was successfully launched in a dual launch with Optus-D2 for satellite operator Optus Networks, Pty. from Australia (SingTel Optus), on October 5th, 2007 on an Ariane 5GS rocket booster operated by launch operator Arianespace from the Kourou Space Port in French Guyana.
