The 746th Test Squadron from Holloman Air Force Base, N. M., provided an array of GPS jamming equipment and support for DT NAVFEST at Edwards AFB, Calif. The jammers provided a degraded GPS environment for testing multiple aerial platforms throughout the week. Testing was done from 1 to 6 a.m. each day to minimize impact on the community and civilian air traffic. (U.S. Air Force photo by Cole Johnson)
