The Galileo Return Link Service, which sends an automatic acknowledgement message to people activating a distress signal, in distress to receive automatic acknowledgement that their signal has been received, was declared operational on January 21.

In the years since civil and commercial use of GPS and GNSS became common in the mid-1990s, a variety of software tools have been developed to perform offline analyses of GNSS performance and data collected from GNSS receivers. Some of these tools are part of commercial software packages such as Matlab [1] or STK [2]. This article focuses on tools that are freely available (as of early 2020) and are standalone or work with commercial software.

Despite a surge of activity at the end of the year, the FCC has not yet ruled on a request by Ligado Networks to use its spectrum for a terrestrial network. It is unclear what will inspire federal regulators to finally decide.
I strode into the plenary session of the ION International Technical Meeting, primed and ready for a barrage of modernity, of out-in-front advances in precision positioning, navigation and timing. The first thing I saw was a 7-foot tall cesium beam tube, an early atomic clock from the 1950s.

A new cloud-based, digital reality visualization platform in the Hexagon AB booth turned heads at the Consumer Electronics (CES) megashow in Las Vegas in early January. HxDR creates accurate digital representations of the real world through the seamless combination of reality-capture data from airborne, ground and mobile sensors.

When Dorota A. Grejner-Brzezinska left her native Poland to study GPS in the United States, little did she know her work there would go on for three decades and take her to the world’s farthest reaches. Today, as University Distinguished Professor, Lowber B. Strange Endowed Chair, Associate Dean for Research, College of Engineering and director of the Satellite Positioning and Inertial Navigation (SPIN) Lab at The Ohio State University, she leads a team of front-line GNSS researchers that is revolutionizing how we map and navigate.

We’ve a long history as a learned society,” Royal Institute of Navigation Director John Pottle told the plenary audience, “solving navigation problems is no longer a simple matter. It’s not all about the technology anymore. What we think we do, uniquely, in the world is to bring different disciplines together who share a common interest in navigation.”

This article investigates and analyzes position solution availability and continuity from integrating low-cost, dual-frequency GNSS receivers using PPP processing with the latest low-cost, MEMS IMUs. The integration offers a complete, low-cost navigation solution that will enable during GNSS signal outages of half a minute, with a 30% improvement over low-cost, single-frequency GNSS-PPP with MEMS IMU integrations previously demonstrated. This can apply to UAVs, pedestrian navigation, autonomous vehicles, and more.

Hexagon AB, a global leader in sensor, software and autonomous solutions, brought its vision of the autonomous future for infrastructure, vehicle mobility and manufacturing to CES 2020 in Las Vegas, Nevada.
A new cloud-based, digital reality visualization platform in the Hexagon AB booth captured the attention of CES 2020 visitors in Las Vegas this week. HxDR creates accurate digital representations of the real world through the seamless combination of reality-capture data from airborne, ground and mobile sensors.
