Consumer Reports - NAVWAR Battery Side by Side Scoring and Assessment

Date/Time: Wednesday, Aug. 25, 5:05 p.m.
This briefing outlines the need for a ‘Consumer Reports’ type benchmarking structure for current and emerging receiver technology wherein an individual receiver’s performance is scored with respect to the whole population. Scores will be compared across multiple categories including baseline performance, tracking through jamming environments, and spoofing resilience. The relative data will provide a broader context as to what constitutes an overall score.
Department of Defense (DoD) has generated thousands of hours of test analysis on military GPS receivers and civilian Global Navigation Satellite System (GNSS) receivers, often drilling down to details or quirks specific to a specific model of receiver. The Rx Consumer Reports explores the value of analysis in the other direction, drilling sideways instead of down. Having a cursory battery to benchmark receiver performance within benign and contested environments and then relating all the results can provide insight into relative vulnerabilities, strengths, and help identify further drill-down testing. Ideally, this resource will provide value not just for military TTPs, but also for developing more resilient receiver systems. Gathering insight on where devices excel or fail can improve the entire product landscape, current and future.
Through our test assets we provide repeatable, uniform, and accurate benchmarking available to entire PNT enterprise. Both GPS only and multi-GNSS batteries are tested. Future test vectors are planned for specific applications such as high-accuracy timing and PNT systems with integrated inertial systems.
This briefing will examine the quantitative results of over 30 commercially available receivers spanning a wide range of affordability, use-case, and susceptibility. Furthermore, the test assets will aim to complement, not replace, existing test standards. The insights from a holistic view will aid in optimizing existing device utilization and improve decision making in future development.
