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.

The authors examine GNSS performance on 27,500 kilometers (17,000 miles) of North American highways to better understand the automotive positioning needs it meets today and what might be possible in the near future with wide area GNSS correction services and multi-frequency receivers.
International astronomers linked observations from eight telescopes, including the the Canadian Hydrogen Intensity Mapping Experiment (CHIME), to pinpoint the location of a repeating fast radio burst (FRB), a little-understood and seldom-observed astronomical phenomenon that may hold keys to the origin of the universe. GPS played an important role in coordinating the telescopes and their milliseconds of data.

A software-driven navigation engine makes consistent, reliable navigation possible in tunnels, garages and urban canyons.
In difficult GNSS signal environments for driving—and here urban canyons, tunnels and parking structures are the standouts—GNSS performance may be severely degraded or completely denied. Inertial aiding has become the standard for ground vehicle navigation. Requirements for autonomous navigation in these circumstances will be rigorous, but those for map-matching, telematics and fleet vehicle tracking are much less so.
