UWB and microwave technology furnish indoor positioning

While many industries benefit from GNSS, others have not though their need cries out loud.  Manufacturing, indoor transportation and logistics, to name a few. Massachusetts-based Humatics furnishes indoor navigation systems for areas where GNSS technology does not perform well. Its core concept is “constellation” installations of high-frequency radio transmitters to enable centimeter- and millimeter-scale microlocation technology for positioning, navigating and collaborating.

Enhanced GNSS Location over 5G Networks Trialed by ESA

Positioning with 5G next-generation cellular technology, based on higher bandwidths and frequencies, promises to open up new possibilities for localization services. As GNSS receivers share their position awareness across more powerful cellular networks, smart traffic management, asset tracking and personalized drone-based delivery will be just three examples of expanded capability. A European Space Agency (ESA)-sponsored test recently simulated this broadening PNT potential.

Vehicle Takes Three on Autonomous Drive from Midwest to D.C.

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.

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.
