Global Navigation Satellite Systems Engineering, Policy, and Design
Today’s vehicular navigation systems couple global navigation satellite system (GNSS) receivers with an inertial navigation system (INS). Low Earth orbit (LEO) satellite signals are a particularly attractive INS aiding source in GNSS-challenged environments.

Spectrum regulators have denied a request for an extension to file comments on a petition to rewrite the rules governing Ultra-Wide Band (UWB), a wireless technology that spreads the content of a signal across hundreds of megahertz of frequencies and poses a potential interference risk to GPS.

Spectrum regulators are considering a request to modify tough restrictions on devices and systems relying on Ultra-Wideband (UWB) technology, an approach to using frequencies that skips across wide swaths of spectrum instead of confining its signals to distinct, narrower bands.

Trimble recently introduced the latest version of its core real-time monitoring software—Trimble 4D Control software. Version 5.0 provides new features that enable users to streamline real-time structural monitoring system deployment as well as simplify the connection to geotechnical sensors. Trimble 4D Control software enables project stakeholders to monitor critical infrastructure such as dams and bridges along with mines and buildings surrounding construction sites and tunnels.

More powerful, accurate, resilient GPS III satellite will help modernize today’s GPS constellation
TITUSVILLE, Florida, July 8, 2019 – The GPS satellite constellation is about to get its next heathy dose of new technology and more advanced capabilities. The second next-generation, Lockheed Martin-built GPS III satellite—nicknamed “Magellan” by the U.S. Air Force—is sealed up and ready for its planned July 25 launch.

Spectrum regulators should hold off on granting a waiver supporting testing of a new UltraWideband (UWB) technology for driverless vehicles until more information is available, the GPS Innovation Alliance (GPSIA) said in comments to the Federal Communications Commission (FCC). In fact the FCC should require a minimum level of information be submitted before considering any UWB waivers or changes to the UWB rules, the GPSIA said.
