What freeware or open-source software packages are available to support GNSS performance evaluations?

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.

Qualcomm’s New Chip: More Power, More Features, Same Ol’ GNSS

In early December, Qualcomm made its annual announcement of a new chip for phones and wearables in the coming year. Qualcomm’s flagship system-on-chip will power a range of devices launching in 2020, with lots of new and exciting (to smartphone addicts) capabilities; just not much—make that nothing—new in satellite-based navigation derivatives. The company’s Snapdragon 865, succeeding the 855 which reigned during 2019, brings support for 5G, 200MP cameras, and 144Hz displays.

Time Is Relative, Position Absolute

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.

Taking the Long View with Dorota A. Grejner-Brzezinska

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.

Lamplights Glisten in the Cold As We Reflect Back – and Forward

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.”
