The proposed research seeks to define new methods in GPS selective denial technology by incorporating a precision frequency reference, knowledge of location and a fully programmable, L-band signal synthesizer that generate signals that exploit specific weaknesses in the GPS C/A and P(Y) signal structures. With this technology, users have complete control over the amplitude, frequency, phase, and beam characteristics, enabling the device to support a wide variety of jamming scenarios and configurations. The resulting system will be flexible, portable, relatively low-cost to manufacture, and has provisions to retrofit existing military receivers at a minimum expense. The concept can also be applied to other positioning systems and communication (broadband or narrowband) systems as well. This includes GLONASS, the forthcoming Galileo, and a variety of cellular communications (for example TDMA / CDMA based cellular systems). Lastly, when used in a coordinated mode, the SDS can operate simultaneously as both a jammer and pseudolite system.
