More than 250 navigators and technologists from 28 countries gathered in Chiba, Japan, just outside of Tokyo for the 16thtriennial World Congress of the International Association of Institutes of Navigation (IAIN) this week.
The theme of the conference was “Science, Technology and Practice to Resilient Navigation.”
While a number of presenters discussed technical aspects of GNSS navigation, the event was notable for its inclusion of many papers dealing with how GNSS information can best be used to optimize operations. Issues such as the impact of weather on optimal ship trajectories and long-distance flights, integration with ship’s ECDIS and AIS systems received considerable attention.
GNSS-independent navigation also received its fair share of attention. Modern positioning using radar, underwater electromagnetic localization, and eLoran were among the systems discussed over the course of the three-day conference.
A plenary panel on the second day addressed several broad resilient navigation issues. The first three speakers addressed GNSS disruptions detected by Europe’s STRIKE3 project, the history of GNSS spoofing, and examples of impacts from GNSS disruption on commercial aviation. With that background the rest of the presenters addressed available technologies to make GNSS receivers much more resilient to GNSS jamming and spoofing, South Korea’s developing eLoran system, and the efforts of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) to encourage resilient navigation technologies and policies.
IAIN also presented a number of awards for outstanding achievement. These included the John Harrison Award for outstanding contribution to navigation by an individual to Dr. Dorota A. Grejner-Brzezinska of Ohio State University, and the Necho Award for long term contribution to the field of navigation to Prof. Bernhard Hofmann-Wellenhof of the Austrian Institute of Navigation. Assistant Professor Taro Suzuki of Waseda University received IAIN’s Sedak Award for presentation of his paper “Evaluation of Precise Point Positioning of Small UAVs using L6E Signal via QZSS.”
