GNSS jam-proof test range ready for customer testing

May 25, 2016By

A new dimension in real-world PNT testing has arrived. One of the most critical things to predict for chips, receivers and devices using alternative or back-up PNT technologies is how they will actually perform without GPS. Filling this need, the U.S. Air Force 746th Test Squadron has declared Initial Operational Capability (IOC) for its new truth reference, the Ultra High-Accuracy... read more

Is reliance on GPS making us lose our mapping minds?

May 16, 2016By

By Tracy Cozzens Managing Editor I love maps. As a child, I was my family’s designated navigator on car trips (or my parents indulged me!). I studied our roadmaps, searching out each legend icon on the map and finding icons to look up on the legend. I would use the map’s indicators to determine the distance between points and interesting... read more

In defense of PNT: Multi-GNSS to the rescue

May 11, 2016By

For more than 41 years, many of us who were there in the beginning have been discussing the attributes, capabilities, enabling features and shortcomings of GPS and other space-based PNT (position, navigation and timing) systems. You have likely heard most of them; historically they go something like this: The signal is weak. The signal is easily jammed. The signal can be... read more

Expert Opinions: What will help regulators, public accept autonomous vehicles on the road?

May 11, 2016By

Q: What advance — or, overcoming what challenge — will most enable acceptance of autonomous vehicles on the road with regulators and the public? A: Similar to airplanes with an autopilot feature, the key issues that must be addressed in autonomous vehicles are redundancy and reliability of systems and appropriate, timely signals to the operator. One key area where this... read more

Amsterdam declaration advances Europe in autonomous driving

Europe has leapt forward in the ragged advance toward autonomous road travel. The Declaration of Amsterdam, “Cooperation in the field of connected and automated driving,” signed April 14 by the 28 transport ministers of the European Union member states, lays out a strong vision of road future. The language shows some pretty steely resolve to see a driverless ground transport... read more

GNSS and the real-time network: The surveyor’s best friend

May 4, 2016By

A lot of talk is being made about UAVs these days and how this technology is going to revolutionize many industries, with surveying being one of the biggest users. I won’t deny the impact this new tool is going to have on our profession (as written in my last column). But I don’t think it will compare to the use... read more

GNSS has bad days, too

April 27, 2016By

“Even the best technology has a bad day,” Charles Schue told the New York Stock Exchange (NYSE), which relies very heavily on the best technology to keep the world’s financial edifice afloat. Vulnerabilities in the stock market were pointed up during a demonstration on April 19, showcasing how one positioning, navigation and timing (PNT) system can cover the chinks in... read more
