Gary Postlethwait, right, and Bert Priest, test technicians with ATK Aerospace Systems of Magna, Utah, make final preparations for testing inside the avionics mounting structure at ATK's avionics test facility in Clearfield, Utah. The avionics system is the "brains" for a launch vehicle, consisting of the electronics system, equipment and associated sensors responsible for controlling key guidance, launch, navigation and recovery hardware.
