Quantitative assessments leveraging effects based analysis for degraded PNT

ABSTRACT: PreTalen recognizes that an ongoing challenge facing the Department of Defense (DOD) and civil/commercial PNT users is the understanding of how integrated systems are impacted by degradation of key information. PNT information is a cornerstone technology that supports increased operational efficiency, productivity, precision, and safety. Because Global Positioning System (GPS) provides such a low cost and accurate method for determining PNT information, our reliance on GPS systems is critical. While some users may understand the need for a backup system, there is no clear method to determine requirements for a backup system to achieve graceful degradation. The problem is confounded by the multiplicity of applications and use of PNT information in each system that is reliant upon GPS. A clear understanding of how the integrated system (host and PNT) uses this data and the resulting effects from a degraded situation requires an in-depth investigation to fully comprehend potential impacts. Currently there is no tool or standardized methodology to evaluate or accomplish these types of assessments. The Quantitative assessments leveraging effects-based analysis for degraded PNT [QUALE-PNT] system will fill this void. This HITL test asset includes algorithms for parametric setup and autonomous analysis across numerous degradation types affecting PNT systems. BENEFIT: PreTalen is looking forward to the QUALE-PNT system becoming a reality as the prospective users are growing daily. PreTalen would like to start with demonstrating QUALE-PNT to Department of Homeland Security (DHS) and their PNT system providers. PreTalen also expects that many test organizations (746, Eglin, JNWC, GPSD, Spawar, Allies/Joint activities) would be likely users as they also currently perform similar tests manually and would see incredible return on investment from acquiring QUALE-PNT capabilities. PreTalen estimates that over 50 QUALE-PNT systems would be required by just the DHS and test organizations and many other state and federal agencies (NASA, OSD, CIA, FAA, etc) would also be interested in these capabilities. While PreTalen is a small company, our employees have been in the Navwar community for decades and have relationships with those that would be interested in the QUALE-PNT systems.
