Attila Komjathy is the Group Supervisor of Near Earth Tracking Systems Group (335S) and a Principal member of the Tracking Systems and Applications Section at NASA's Jet Propulsion Laboratory (JPL), the California Institute of Technology, specializing in remote sensing techniques for terrestrial and planetary applications.
He received his Ph.D. from the Department of Geodesy and Geomatics Engineering of the University of New Brunswick, Canada where he currently also serves as an adjunct professor. Dr. Komjathy spent four years as a postdoctoral researcher at the University of Colorado at Boulder. He is recipient of several NASA awards including an Exceptional Space Act Award, Best Paper and JPL Group Achievement Awards. Dr. Komjathy is JPL’s primary interface to the GATEW working group (Global Navigation Satellite System Augmentation to Tsunami Early Warning System) under the leadership of IUGG and IAG . He is an Editorial Board member of the AGU’s Radio Science and also served as associate editor for Springer’s GPS Solutions – the Journal of Global Navigation Satellite Systems. In addition, he serves as Commission Chair for the URSI National Committee “Ionosphere and Radio Propagation” since 2018. The US Institute of Navigation elected Dr. Komjathy as a Fellow for contributions to remote sensing of Earth’s ionosphere using GNSS signals in 2015.

Dr. Komjathy investigates GPS and other sensors to study the temporal and spatial variation of the global ionosphere including the use of global empirical, physics-based and assimilative ionospheric models. Specializes in developments of real-time remote sensing techniques conducting research in natural hazards detection of earthquakes, tsunamis, volcanic eruptions using ground- and space-based GNSS data and infrasound measurements. Dr. Komjathy leads new activities that expand the group’s focus beyond GNSS-related remote sensing techniques, targeting novel terrestrial and planetary applications including planetary surface and atmospheric coupling.
Dr. Komjathy’ team developed two innovative techniques to potentially detect and measure seismicity on Venus: 1) an orbiting infrared camera to look for seismic-wave-generated Venus airglow perturbations and 2) infrasound detection using balloon platforms on Venus. Dr. Komjathy designed, organized and conducted major Earth analogue field experiments to test precise pressure sensors to detect infrasound signals using aerostats and piloted hot-air balloons.
