User Equipment (UE) Cognitive Functions

Emerging 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 (SDR) in response to stimuli in the external environment. Under the Phase I effort, we applied these CR technologies to develop a design for a cognitive GPS UE that would be aware of its surrounding radio frequency (RF) environment, and could adapt its functionality to optimize its PNT solution. Under this Phase II SBIR effort we propose to build a prototype GPS Spectrum Sensing Cognitive Radio (SSCR) that will include adaptive GPS services for enhanced performance in the presence of jamming, spoofing, multi-path and signal fading environments (such as urban operations). We shall implement and test Cognitive Engines that adapt the signal tracking and navigation performance parameters based on the current mission needs. The prototype SSCR will leverage an existing GPS SDR and will be integrated with a sophisticated Cognitive Engine Test Bed to support automated decision making. A combination of simulated GPS environments and live testing will be used to demonstrate the operational improvements that could benefit future generations of Military User Equipment by adopting the SSCR architecture. 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.
