Deep-Space Clock Could Blaze Trail to Improved GNSS Accuracy

The U.S. National Aeronautic and Space Administration (NASA) has activated an orbiting ultra-precise atomic clock orbiting aboard a spacecraft provided by General Atomics Electromagnetic Systems. If the clock performs as well in space as it has in the lab, losing only one second every 10 million years, the technology could enable far-reaching deep space missions—and improve the accuracy of GNSS timing and positioning.

New-Age Satellite-Based Navigation STAN: Simultaneous Tracking and Navigation with LEO Satellite Signals

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.

With Extension Request Denied, Comments on UWB Petition Due to FCC August 19

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.

FCC Weighs Broad Changes in Ultra-Wideband Rules

GPS Innovation Alliance Asks for More Time to Respond

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.
