Dr. Robert W. "Bob" McGwier is an applied mathematician and signals-processing specialist whose professional biography spans NSA-affiliated cryptology research, academic leadership in RF engineering and spectrum science at Virginia Tech, and the co-founding of two commercial ventures — including satellite geolocation company HawkEye 360.123 Since retiring from Virginia Tech he has directed his technical background toward civilian UAP detection, founding UAP Tracking Network, Inc. and advising the sensor-fusion startup Skywatcher, LLC.45
Education and Early Career
McGwier holds a B.S.E.E. and a B.S. in Applied Mathematics from Auburn University and a Ph.D. in Applied Mathematics from Brown University, awarded in 1988.2 For approximately 25 years he served as a member of the technical staff at the Institute for Defense Analyses' Center for Communications Research in Princeton, New Jersey — an NSA-affiliated research unit — where he applied advanced mathematics to cryptology and signals intelligence problems.2 This posting provided both deep technical grounding in signal detection and long exposure to the classified world of national-security sensing, neither aspect of which is independently verifiable in open sources by design.
Virginia Tech Hume Center
In 2011 McGwier joined Virginia Tech as Director of Research and later Chief Scientist at the Ted and Karyn Hume Center for National Security and Technology, with a joint appointment as Research Professor in the Bradley Department of Electrical and Computer Engineering.12 He is credited with growing the center's research portfolio approximately tenfold during his tenure. His technical program there spanned 5G security, machine learning applied to RF signals, spectrum dominance, and software-defined radio. He co-advised the Virginia Tech team in the DARPA Spectrum Challenge and chairs the ARRL SDR Working Group under the amateur radio call sign N4HY.1 McGwier retired from Virginia Tech around 2020–2022.
Commercial Ventures
McGwier co-founded HawkEye 360 in September 2015 alongside Chris DeMay and Charles Clancy.3 The company operates a small-satellite constellation that geolocates RF signals for geospatial intelligence, serving defense and commercial customers; it has grown into a commercially significant entity in the RF geolocation market.3 He also co-founded Federated Wireless, a spectrum-sharing technology company. Both ventures draw directly on the signals-processing and spectrum expertise he developed across his IDA and academic careers.
UAP Detection Work
Following his retirement, McGwier channeled a long-standing personal interest in anomalous aerial phenomena into organized research. He founded and serves as president of UAP Tracking Network, Inc., which aims to apply artificial intelligence and automated sensor systems to the continuous detection and tracking of anomalous aerial phenomena.45 He also joined the Board of Advisors of Skywatcher, LLC — a civilian UAP detection startup founded in 2024–2025 by Air Force veteran Jake Barber and technologist James Fowler — which deployed a multi-sensor fusion platform combining electro-optical, infrared, radar, and passive RF sensors.4 McGwier has spoken at UFO CON (2021, 2023, 2026) and the UAP Summit, and appeared on podcasts including the Richard Dolan Members channel, where he also served as a senior moderator.6 He describes a personal "missing time" experience during his Auburn University freshman year as a formative motivator for his interest in the subject.
Skywatcher and Evidentiary Limits
Skywatcher attracted substantial public attention in 2024 with promises of a large public data release of more than 10 TB, peer-reviewed publications, and video evidence of anomalous phenomena.789 As of early 2026 the project has produced no peer-reviewed papers and no comprehensive data release, and its public communications channel went silent after December 2025.78 Critics in the UAP research community describe early released footage as depicting mundane objects such as balloons, and commentators have labeled the episode "The Skywatcher Silence."78 McGwier's advisory role therefore associates his technical credibility with a project that has not yet delivered on its central scientific commitments.
More broadly, McGwier has publicly described personal encounters with Unidentified Submerged Objects during classified operations, though these claims are unverifiable by design and have not appeared in any peer-reviewed publication.56 His core professional credentials — IDA/CCR cryptology research, Virginia Tech Hume Center leadership, and co-founding of HawkEye 360 — are well-documented and undisputed.12310 The UAP-specific claims and the scientific outputs of the sensor networks he has backed remain unverified by independent sources.
