The recent C4ADS report on GPS spoofing in Russia and the Middle East provided a number of interesting and new revelations. One of which was that GPS interference can be detected from space.
Working with a sensor aboard the International Space Station, a team lead by Prof. Todd Humphrey’s of the University of Texas and Dr. Scott Budzien of the Naval Research Laboratory were able to detect and geo-locate a disruption source to within 10km. Here is a presentation on how it was done.
RNT Foundation believes this holds great promise for navigation and user safety world-wide. We have engaged with the US government in an effort to establish a global common-operational picture of GPS disruptions to help users protect themselves.
