USA-207,[4] international COSPAR code 2009-047A,[5] also known as PAN, officially meaning Palladium At Night,[6] or P360[7] is a classified American communications satellite,[8] which was launched in September 2009. The US government has not confirmed which of its intelligence agencies will operate the satellite.[9] The spacecraft was constructed by Lockheed Martin, and is based on the A2100 satellite bus,[6] using commercial off-the-shelf components.[7] The contract to build PAN was awarded in October 2006, with the satellite initially scheduled to launch 30 months later, in March 2009.[10]
PAN was launched by United Launch Alliance using an Atlas V 401 carrier rocket, with the serial number AV-018. The launch, from Space Launch Complex 41 at the Cape Canaveral Air Force Station, occurred at 21:35 GMT on 8 September 2009, at the start of a 129 minute launch window.[11] PAN successfully separated from the rocket just under two hours after liftoff.[12]
PAN has shown an unusual history of frequent relocations, moving between at least 8 different orbital slots since launch: as of January 2013 it is located at 42.5 deg E.,[13] over East Africa.
