Companies Look for Alternatives to Google Maps, but Location Giant Chugs Along…

April 10, 2012By

The big news at the recent O'Reilly Where 2.0 and GPS-Wireless conferences, both located in the San Francisco Bay Area, may be continued industry fallout from Google’s decision to start charging higher volume users. Location-based services may have jumped the shark, as one Nokia executive said at GPS-Wireless, but such deals as Foursquare's partnership with American Express can only help grow consumer awareness and drive mobile purchases. Indoor positioning and connected vehicles continued to be a hot topic at both Where 2.0 and GPS-Wireless. Yet, at least one executive at GPS-Wireless said that "the year of LBS has come and gone — and nobody noticed it." read more

Expert Advice: Soldiers and Civilian GPS: Dangerous (and Deadly?) Expediency

April 1, 2012By

An old adage says, “Be careful what you wish for, you might get it.” That is particularly relevant in today’s world of GPS and the positioning, navigation, and timing (PNT) dependencies it has created. In business, it’s all about location, and in military circles, something called real-time situational awareness, driven by the ready availability of PNT from GPS. However, it has been reported (and validated by experience) that U.S. soldiers believe that the GPS equipment they are issued through official channels is too big, too heavy, uses too many batteries, and is old-looking and not sexy like the multi-color, multi-app personal electronics and smart phones they are accustomed to at home. read more

Out in Front: Independence: A National Value

April 1, 2012By

Advanced low-frequency (LF) signals are back on the air in North America, with live testing of a wide-area precise-timing solution. Initial tests include a comprehensive pallet of signals, including eLoran, that are being evaluated for their ability to provide a robust, wide-area, wireless precise-timing alternative that can operate cooperatively with GPS, or during periods of GPS unavailability. read more

Navigating the Moon

March 28, 2012By

The European Space Agency has issued an intriguing Intended Invitation To Tender, “Weak GNSS Signal Navigation on the Moon.” The study will investigate use of weak-signal GPS/GNSS — and of course ESA is interested primarily in the use of Galileo — for real-time position, navigation and timing information to various future lunar assets such as automated landers, rovers, Earth-Moon transportation vehicle, in-situ navigation, and so on. read more

Automakers Move Ahead on Mobile Connectivity

March 21, 2012By

It wasn’t quite a call to arms, but Bill Ford, head of Ford Motor, called on the wireless community to work with car makers to avoid global gridlock and create a future of “urban mobility,” a network that will track vehicles and automatically instruct cars to change lanes, exit a road, or park. Vehicle connectivity was one of the major themes of the Mobile World Congress, held in February in Barcelona. For some of us, it brought up memories of the PATH automated highways project of the 1990s. You have likely seen photos of that prototype automated highway with platoons of driver-less vehicles riding on I-15 in southern California. The vision has changed, and we are headed towards autonomous, connected vehicles and away from the specialized, and prohibitively expensive, infrastructure that defined earlier efforts. read more

eLORAN and UrsaNav: Timing Is Everything

March 14, 2012By

The first part of the recent UrsaNav press release says it best: This week for the first time since August 2010 advanced low frequency (LF) signals, including a new eLORAN, are on the air in North America! As a result of a Cooperative Research and Development Agreement (CRADA) between the United States Coast Guard (USCG) and UrsaNav, Inc. live testing... read more

The Kinematic GPS Challenge: First Gravity Comparison Results

March 14, 2012By

By Theresa Diehl The National Geodetic Survey (NGS) has issued a “Kinematic GPS Challenge” to the community in support of NGS’ airborne gravity data collection program, called Gravity for the Redefinition of the American Vertical Datum (GRAV-D). The “Challenge” is meant to provide a unique benchmarking opportunity for the kinematic GPS community by making available two flights of data from... read more
