Global Navigation Satellite Systems Engineering, Policy, and Design
Autonomous vehicle research firm VSI Labs took its show on the road in September, as a three-member team was driven—by their autonomous car—on a thousand-mile journey from Minneapolis to Washington D.C. The Drive East employed Trimble’s precise point positioning (PPP) technology, Trimble RTX, delivering GNSS corrections via satellite or cellular.

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.

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.

Septentrio, a manufacturer of high-accuracy GPS/GNSS technology for demanding applications, is providing positioning technology to Artisense, supplier of innovative computer vision solutions for automated vehicles. Artisense incorporates Septentrio GPS/GNSS in their latest Visual Inertial Navigation System (VINS), which was just demonstrated at the Auto.ai show in Berlin, Germany on September 25-27, 2019.

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.

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.
