European Space Agency (ESA) top brass welcomed journalists to the Agency’s headquarters in Paris for its annual New Year’s press launch. On hand was the Director General as well as ESA’s Galileo guru Paul Verhoef, who spoke one-on-one with Inside GNSS.By Peter Gutierrez
The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.By Dee Ann Divis
An Android mobile application, GNSS Compare can provide a real-time position using Galileo and GPS dual frequencies. It directly logs data from the real-time algorithms, and the retrieved files are used for analysis.By Ciuban & Krainski, et al.
A wheel-mounted inertial measurement unit provides high-rate (2 kHz) bias-free data for vehicle navigation, road-quality measurement systems and instantaneous wheel dynamics estimation for vehicle stability control.By Oleg Mezentsev & Jussi Collin
The Galileo program is about to launch its eagerly anticipated navigation message authentication service. It will be no panacea but the first step in a gradual process of fully securing one of the fundamental technologies of the 21st century.By Peter Gutierrez
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  or STK . This article focuses on tools that are freely available (as of early 2020) and are standalone or work with commercial software.By Sam Pullen
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.
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.By Peter Gutierrez
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.”By Peter Gutierrez
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.
Hours before an impending government shutdown, the President signed both the defense appropriations and authorization bills on Friday, December 20. The bills funded nearly all of the Air Force’s GPS program but made substantial cuts in Army GPS receiver development.By Dee Ann Divis
Reducing the number of GPS receivers installed or carried while tapping multiple PNT sources.
Prototyping and beta testing are techniques closely associated with Silicon Valley, the innovation engine admired around the world and, in particular, inside the Pentagon. Simply introducing a new idea has been known to take years in these halls; witness the long introductory saga of GPS itself in the 1970s.By Dee Ann Divis
