User Equipment (UE) Cognitive Functions

merging Cognitive Radio (CR) technologies are allowing the development of radios that can “observe,” “orient,” “plan,” “decide,” “learn,” and “act” to adapt the performance of a Software Defined Radio in response to stimuli in the external environment. By applying these CR technologies to enhancing Position, Navigation and Timing (PNT) performance, a cognitive GPS UE can be designed that would be aware of its surrounding radio frequency (RF) environment, and could adapt its functionality to optimize its PNT solution. Under this SBIR effort we propose to develop a GPS Spectrum Sensing Cognitive Radio (SSCR) that will include adaptive GPS services for enhanced performance in the presence of jamming, and spoofing, multi-path and signal fading environments (such as urban operations). Intelligent software algorithms that dynamically adjust location accuracy vs. power based on the current mission needs will also be included. The SSCR will be developed leveraging existing software GPS receiver components and integrated with a sophisticated Cognitive Engine Architecture to support automated decision making. An SSCR test-bed will be designed that can be used in Phase II to demonstrate the operational improvements that could benefit future generations of Military User Equipment by adopting the SSCR architecture to be developed under this effort. BENEFIT: The NAVSYS Cognitive GPS UE will enable the military to deploy GPS UE with the ability to adapt to optimize performance in different environments. This improved positioning and navigation capability will shorten battles and save lives. The same technology can be applied to benefit civilian public protectors who will be able to execute their tasks more efficiently.
