On Feb. 11, the European Union (EU) celebrated 112 Day in honor of the single European emergency phone number. The 112 system uses Advanced Mobile Location (AML) to receive location information from mobile phones. Every year, about 300,000 people who call the emergency services cannot describe their location because they may not know where they are, because they are too... read more

KU Leuven: Galileo signals will become more difficult to falsify

Galileo satellites (EU).

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

DoverAFB-GPSIIIA-4-O

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, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By
To improve precision navigation, a second-generation SBAS will use signals from both GPS and Galileo, and dual frequencies, to achieve even greater GNSS integrity and accuracy.

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

Tracking RFI: Interference localization using a CRPA

February 7, 2017By
Eurocontrol-airtrafficcontroller-airlines-O

A controlled radiation-pattern antenna can preserve GNSS positioning while providing at least an azimuth angle towards an interference source. If integrated with an attitude and heading reference system, only a few lines of position pointing towards the RFI source could provide a fast indication of the probable ground location. read more
