Two Years Later, SBIRS Geo-1 Finally Declared Operational

摘要

The first of a new generation of U.S. missile warning satellites, the Space Based Infrared System (SBIRS) Geo-1, was quietly declared operational last month, two years after its launch. Air Force Space Command declared SBIRS Geo-1 operational May 17 and recommended Integrated Tactical Warning and Attack Assessment certification of the asset to U.S. Strategic Command, Air Force Lt. Connie Dillon, a Space Command spokeswoman, said June 7 in response to a SpaceNews query. The Air Force has attributed Geo-1's lengthy commissioning period to an onboard communications issue correctable via a software upload.
