A ground equipment problem has caused a 24-hour delay in launch of the first GPS IIF satellite (GPS IIF-SV1).
During normal processing for the launch from Cape Canaveral, Florida, mission managers determined that a piece of ground support equipment used to control one of the swing arms on the fixed umbilical tower was not operating correctly and needed replacing.
Replacing the GSE component will add one day to launch processing, according to the United Launch Alliance managers. This will be the first launch of a GPS satellite on the Boeing Delta IV rocket.
