The U.S. Department of Defense will use in-theatre jamming of the LI signal to deny its adversaries the use of GPS. While jamming GPS signals has always been a military option, its use became a necessity following deactivation of Selective Availability. In addition to such military procedures, terrorists might try to jam the GPS signals using easily constructed equipment. GPS signals are also susceptible to unintentional jamming from neighboring users of the radio spectrum. Jamming signals can take different forms, and just how a receiver responds to a jamming signal depends on several factors. In this month's column, two Norwegian authors describe the influence of different types of jamming signals on the ability of LI C/A-code GPS receivers to acquire and track satellites under various circumstances and they report the results of testing three different receiver types using an advanced GPS simulator system.
