Researchers from the Department of Electrical Engineering at KU Leuven (University of Leuven, Belgium) have designed authentication features that will make it more difficult to send out false Galileo signals. Professor Vincent Rijmen and doctoral student Tomer Ashur from the Department of Electrical Engineering (ESAT) at KU Leuven have advised the European Commission on ways to make Galileo signals more... read more
Quick, what’s the best alternative when GNSS signals are not available? This is not a simple question, but we’re asking for a simple answer. Among the multiple avenues pursued at the U.S. Defense Advanced Research Projects Agency (DARPA), as described in February’s PNT Roundup, which has the most promise? Inertial sensors Chip-scale atomic clocks Cell signals Low-Earth orbit communications satellites... read more
Thanks in part to a Team Dover aircrew, the next generation of Air Force GPS satellites will soon be launched into orbit. A C-17 Globemaster III, operated by the 3d Airlift Squadron, transported a GPS Block IIIA Satellite Pathfinder and its shipping container from the Space Coast Regional Airport in Titusville, Florida, to Buckley Air Force Base, Colorado, Jan. 29-31.... read more
Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more
OEM Anti-jammer Israeili device to prevent GPS disruptions The GPSdome anti-jammer was developed for civilian applications. It aims to curb situations in which civilian vehicles are stuck “off the grid.” It combats electromagnetic warfare by using null steering, a method of spatial signal processing through which a transmitter can nullify communication jamming. In particular, the product was developed to address... read more
Researchers at NASA’s Armstrong Flight Research Center have designed an antenna-mounting platform to provide users satellite-based tracking functions for unmanned aerial vehicles. The platform integrates multiple capabilities onto one low-cost platform. In August 2016, NASA signed a license agreement with Mobile Antenna Platform Systems Inc. to commercialize the portable antenna platform. The platform is built to rotate 60 pounds of... read more
