C-TRAC's PNT Technology Showcase was designed to explore PNT alternatives in a GPS-denied environment, part of a large-scale effort to decrease US reliance on GPS technology. The Showcase was sponsored by C-TRAC, CyberWorx and the TechMarketplace. 

Ryan Blay, a graduating senior from CU Boulder’s Colorado Center for Astrodynamics Research (CCAR),  presents a hybrid algorithm that combines Time-Difference-of-Arrival (TDOA) and Power-Difference-of-Arrival (PDOA) localization techniques in order to determine the position of a [GPS-blocking] jammer/ spoofer in a wider variety of situations. 

Catalyst Accelerator has opened applications for companies to join their Positioning, Navigation and Timing (PNT) Innovation Cohort. The Air Force is looking for a suite of options to augment, supplement, backup, complement, and/or improve current PNT capabilities provided by GPS.
