Expert Advice: GNSS Interference, Detection, and Mitigation

May 1, 2011By

Interference, detection, and mitigation — these have become topics of paramount importance to the GNSS community recently, surpassing at times even those old familiar standards accuracy, availability, and integrity. In March, a large expert audience attended a GNSS Interference, Detection, and Mitigation (IDM) conference at the United Kingdom’s National Physical Laboratory near London. My conclusions first, followed by reportage of the details. read more

Out in Front: Blinded by the Light

May 1, 2011By

To illustrate the fix we’re in, Logan Scott offered this analogy for out-of-band interference during the April webinar, “LightSquared and GPS: Our Story So Far.” We’re driving at night and come upon a bicylist with one of those little flashing lights. That’s the GPS signal. So far, so safe. We know the bicyclist’s position. Then around the bend comes a truck with its headlights on high-beam, in the adjacent lane, but brights set at our eye level. That’s the LightSquared signal. Where’s the bicyclist? Uh oh. read more

Indoor Location on the Move

April 20, 2011By

It’s coming. Indoor location, which has been stymied by the limitations of GPS and lack of mapping, is finally getting some legs and is heading us towards seamless navigation. A shopper is guided from home to an empty parking space at the mall, and the navigation doesn’t miss a beat as he heads inside and gets directions to a particular store, and perhaps to a given shelf. Today, the location of a wireless device usually cannot be determined more precisely than the building it is within. In tall or sprawling venues like arenas, malls, dormitories, or apartments this is a critical problem for emergency personnel trying to locate a person who has dialed 911. Mobile marketing and social network applications have also been constrained by problems in obtaining indoor location. read more

Mobile Epiphany – Round Two

April 13, 2011By

Many of you may remember my one and only software review of a product called Touch Inspect back in December 2009, by a Denver, Colorado (Aurora)-based company called Mobile Epiphany. At the time I promised an in-depth review the software “real soon.” Well, real soon has turned into 16 months, and not a single week has gone by that I have not received several e-mails wanting to know more about the software and asking when the next review would be published. So for all of you who have been waiting, this is the promised in-depth review of Touch Inspect version 2.0, which the company now promotes as customizable software tools under the more apt heading of “Mobile Business Process Software.” But the base program is still known as Touch Inspect. read more

How Does the Potential AT&T Acquisition of T-Mobile Affect the Location Industry?

April 12, 2011By

Now that CTIA is over, and without a lot of location-based services news at the Orlando show, the time is ripe to examine the potential blockbuster AT&T acquisition of T-Mobile and how it affects the location industry. In the meantime, is Apple trying to get its mapping initiatives stronger to compete with other heavyweights? Does this include trying to be its own map database provider? read more

Out in Front: Dual Use, Single Front

April 1, 2011By

As it was in the beginning, now and always, and to the ages of ages — or at least into the conceivable near future: GPS was, is, and shall be a dual-use system. Why, then, reading through the March 15 report of the Technical Working Group (TWG) to the FCC on LightSquared/GPS interference, do we find no mention at all of military receivers? read more
