A year-long project aboard a commercial cargo ship collected tens of thousands of snapshots of radio-frequency interference in the GNSS band on a passage from Spain to Korea and back. Most interference was detected in busy port areas, less interference while transiting along coasts, and while least frequent, interference was still found in the open ocean. Researchers at the German Aerospace Center (DLR) are still analyzing the vast amount of GNSS disruption data collected during […]

Photo: ESA-Anneke Le Floc’h Gazing through soaring plexiglass walls at the space simulation room of the European Space Agency’s Test Center in the Netherlands affords a glimpse into scientific history. I felt a frisson, a highly regimented frisson if you will, of vicarious thrill for the rigors, rhythms and methods of research and testing as I toured the center after giving a keynote at the agency’s Navigation Days. Here, the final birthing touches were administered […]

Interval training for the win Short intervals of working out at high intensity followed even shorter recovery periods. This is the basis for Tabata training, and more generally speaking for the wildly popular phenomenon of  HIT (or HIIT, High-Intensity Interval Training), which has been recommended by fitness experts for some years now as a tool to burn fat and increase muscle. Total calorie burn is very high in comparison to conventional training methods, and the […]
