Da Capo: Pardon Me, Boy, Is That the Galileo Choo Choo?

February 1, 2012 - By

Our Paris correspondent, Ms. Axelle Pomies, writes that “The Galileo Train is about to depart, but European GNSS applications incentives are still at the station.” “Despite a vast potential for industry growth and new jobs in Europe,” she continues, “European government bodies are not taking up the challenge. The budget dedicated to GNSS application research in European Commission FP7 was... read more

Patch Antennas for the New GNSS

February 1, 2012 - By

Small ceramic patch elements offer nearly perfect single-frequency receive characteristics and have become the standard for GPS L1 antennas. However, the new generation of GNSS receivers now being introduced track many satellites in multiple constellations. Are these narrow-band devices up to the task for wider bandwidths? read more

Out in Front: When the Gavel Comes Down

February 1, 2012 - By

Perhaps you don’t track suspected criminals in your spare time, nor do you design or supply a GNSS product that does so. Still, the fresh Supreme Court ruling on GPS use for this purpose reverberates for you, in ways yet unknown. The most interesting part of the court’s ruling pops up in a somewhat open-ended “what if” comment concerning future issues that at least one justice thinks the court should address. read more

Shadow Matching: Improved GNSS Accuracy in Urban Canyons

February 1, 2012 - By

GNSS positioning in dense urban areas is unreliable, with accuracy particularly poor in the cross-street direction. One solution is shadow matching, a new positioning technique that uses 3D building models to predict which satellites are visible from different locations and compares this with the measured satellite visibility to determine position. This article presents test results of a preliminary shadow-matching algorithm in a London urban canyon and discusses the practical implementation of the technique. read more

Expert Advice: Getting to Accurate Everywhere Location

February 1, 2012 - By

In the next two to four years, mobile device location platforms will be able to provide positioning performance that enables emergency call (E911) and location-based services (LBS) with excellent accuracy (5–10 meters) in all locations. We call this accurate everywhere location, and it will be a significant enabler of indoor navigation applications and for even wider adoption of consumer LBS. In fact, we may eventually forget how we ever lived without it. This technology can enhance our lives by enabling our mobile devices to know precisely where we are at all times. Armed with this information, our devices can behave in a way that suits our specific situation, and they can do this without us having to do anything other than keep the phone with us. read more
