Lessons to be Learned from Galileo Signal Outage

Every GNSS has experienced a failure. On January 26, 2016, an error in the GPS data upload system caused incorrect data to be transmitted from the satellites on the L1 band used by most commercial GPS receivers. Th e problem was resolved within six hours, although some users experienced problems for as much as twelve hours. Th e next day, the US Air Force (USAF) released a full statement explaining that the problem was caused by ground system soft ware when one satellite was decommissioned.

Ultra-Wideband Re-Emerges As GPS Interference Issue

Seventeen years after federal regulators restricted a promising wireless technology to protect GPS and other spectrum users, they are being asked to loosen those limitations. Ultra-Wide Band (UWB) proponents insist the strictures are too tight and cut off their ability to innovate. In June, Robert Bosch LLC formally requested the Federal Communications Commission (FCC) do what it said it would do back in April 2002: reexamine controls on UWB that the FCC itself called “extremely conservative” when they were written. The request is not to change the rules—not just yet anyway—but for the FCC to launch a rulemaking process that could eventually lead to changes in the rules. And Bosch wants a lot of changes.

Detecting and Geolocating Jammers and Spoofers

Due to the proliferation of personal privacy devices and other jamming sources, it is imperative for safety-critical GNSS users such as airports and marine ports to be situationally aware of local GNSS interference. This article proposes and validates an enhanced method for geolocating GNSS interference sources so that jammers and spoofers can be found and disabled.

GBAS Installations Will Proceed at Airports Across Europe

A European aviation industry alliance will deploy new-generation GNSS-based landing systems, ground-based augmentation systems or GBAS, at airports across the continent, starting this year and gaining momentum in 2020. The GBAS Alliance includes airlines and aircraft manufacturers who will complementarily equip their planes with GBAS reception equipment. GBAS is recognized as a supplement to and future replacement of instrument landing systems (ILS).
