Transition I3 - I4 in the AOR (W)

Inmarsat’s F-2 spacecraft, commonly known as AOR (W), launched from sea on November 8, 2005. Successfully completing in-orbit testing at 8 degrees East during the week of December 12th, the satellite soon after began its scheduled drift to 53 degrees West – its operational location. January 11, 2006 at 11:00 UTC (6:00am EST) marked the completed transition of existing services to the new satellite.
