More than Navigation: Who Cares Where Starbucks Is?

October 25, 2011 - By

The location industry is evolving. In the near future we won’t be discussing navigation and mapping as a way of finding the nearest Starbucks. Contextual location driven advertising will start delivering solid revenues, as soon as the market becomes better organized. The value of location information will be magnified as it shifts to the cloud. Vehicle manufacturers will be creating their own rich contextual location information. Near field communication, NFC, with its seat between consumers and cash registers, will provide some of the most valuable location data. These are points all made at last week’s LocNav conference by The Where Business. read more

Faster than a Speeding Light Particle

October 21, 2011 - By

We published a news story recently suggesting that Albert Einstein, the Mighty Hip Einie, got one thing wrong, or at least not quite totally right: the universal upper limit constituted by the speed of light. Precise-timing GPS receivers in a Geneva lab helped indicate that subatomic neutrinos can travel at a velocity just a smidge faster than the speed of light. Someone at a burning idea factory in the Netherlands riposted that the scientists erred in their conclusion because they failed to take into account the relative movement of the GPS clocks in space and thus miscalculated the neutrinos' time of flight. We hereby refute that assertion with our heavy-lifting Innovation columnist, Richard B. Langley. read more

LightSquared: The So-Called “Fix”

October 21, 2011 - By

LightSquared’s been in the news quite a bit since my last Survey Scene newsletter a month ago, but very little of it has actual consequence. A lot of the “news” is just noise. LightSquared pumped up its propaganda campaign nationwide to try to build a consensus in their favor and put pressure on the FCC, and is threatening a lawsuit if the FCC doesn’t do what LightSquared wants. No surprises there. However, other things have happened that I think you might be interested in hearing about. read more

Steve Jobs’ Impact on Defense; plus CGSIC, ION

October 11, 2011 - By

Like many who had the pleasure of interacting with the genius that was Steven Paul "Steve" Jobs, I have been reflecting recently concerning his incredible impact on our lives. Indeed his impact on every aspect of our lives including GPS is almost beyond description. For example, our warfighters are increasingly using iPads and iPhones in theater for multiple functions, including some dedicated and warfighter-developed GPS applications that far outshine any GPS application provided by the government. When will we learn that we must provide our warfighters what they need or they will go elsewhere to find it because lives are at stake? Today many of our warriors are developing their own applications on their individual iPads and iPhones, exactly as Steve Jobs intended. read more

Car Jammers: Interference Analysis

October 1, 2011 - By

Open-field tests of jamming signals from widely available in-car jammers, measured with an experimental software receiver that records the intermediate frequency (IF) samples, enable a detailed analysis of interference effects from these looming threats. read more

The System: Compass Signal ICD this Month

October 1, 2011 - By

The long-awaited signal interface control document (ICD) for China’s growing GNSS will appear this month, according to representatives of the system who spoke in a “Compass: Progress, Status, and Future Outlook” workshop as part of ION GNSS and the CGSIC meetings in Portland in September. The ICD has been rumored to be available previously to receiver manufacturers within China, creating... read more
