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.

GNSS Transceiver: Simulation Accuracy Assessment of Using a Vector-Tracking Receiver as RF Constellation Simulator

In this article, the authors use a vector tracking approach to convert a software receiver into a software transceiver, showing that this effort is both feasible and easily realized. The basic concept is presented with an accuracy assessment of the error sources and generated signal quality is compared to theoretical lower limits.

GNSS & The Law: Collecting and Processing Geolocation Data

UNDER THE EUROPEAN GENERAL DATA PROTECTION REGULATION

Geographical information plays a permanently increasing role in our society. More and more devices and applications use and process geographical information to serve all kinds of purposes. Smartphones, cars, e-bikes, scooters or foot shackles for law enforcement purposes collect and process geographical information on a permanent basis. Here, we take a close look at privacy issues and the data protection perspective, namely considering the European GDPR and experiences gained one year after its entry into effect.
