Boston, MA — MIT Professor Dr. Kerri Cahoy, an expert in radio occultation, invited Dr. Todd Humphreys to present on development of the FOTON GPS radio occultation receiver. The presentation was an Invited Enrichment Lecture for her graduate-level Satellite Engineering class and other students and faculty of the MIT AeroAstro department. Coincident with Dr. Humphreys’s visit, students Ingrid

Portland, OR — Dr. Todd Humphreys chaired an ION GNSS 2011 panel session on “Improving Security of GNSS Receivers.” Dr. Humphreys began the panel with introductory remarks [pptx] noting the increasing trend of spoofing research over the past few years and also presented on practical cryptographic civil GPS signal authentication [pptx]. The panel consisted of five members from industry and academia: Logan

Austin, TX — Outside of the four papers contributed solely by RNL to ION GNSS, RNL members were co-authors on four other papers: Ryan Mitch’s paper on Signal Characteristics of Civil GPS Jammers (Cornell) Brady O’Hanlon’s paper on CASES: A Smart, Compact GPS Software Receiver for Space Weather Monitoring (Cornell) Mark Psiaki’s paper on Civilian GPS Spoofing Detection based on

Portland, OR — Six members of RNL attended ION GNSS 2011 in Portland, Oregon to present research. Four papers were presented: Characterization of Receiver Response to a Spoofing Attack A Proposed Navigation Message Authentication Implementation for Civil GPS Anti-Spoofing Tightly-Coupled Opportunistic Navigation for Deep Urban and Indoor Positioning An Evaluation of the Vestigial Signal Defense for Civil

Whether it’s investigating ways to preserve the security of GPS signals or developing new types of receivers, the field of radionavigation is ripe with possibility—and Dr. Todd Humphreys does not hesitate for a moment in defining how his research team fits into the mix. “What’s the next big thing in GPS?” he asks. “That’s what

Austin, TX — Dr. Todd Humphreys briefed the United States Patent and Trademark Office via webcast on the state of the art and future trends in radionavigation on Thursday, 14 April 2011. Examiners were present from the main USPTO site as well as satellite locations. Dr. Humphreys talked about: Overview of Radionavigation/GPS Advances in Weak-Signal GNSS Tracking
