Out in Front: The Quick Quid

July 1, 2012By

Maybe we should take it as validation, an acknowledgment of the worth, maturity, and promise of the GNSS industry, that profiteers show up trying to make a fast buck. A prompt pound, a quick quid. Or perhaps we should be angry at this violation of international trust, this grasping effort to monetize the free and open exchange of scientific ideas, this contravention of the very spirit and tradition of global navigation satellite systems and signals. read more

Looking Closely at Received GPS Carrier Phase
The stability of a received GPS signal determines how well the receiver can track the signal and the accuracy of the positioning results it provides. While the satellites use a very stable oscillator and modulation system to generate their signals, just how stable are the resulting phase-modulated carriers? In particular, do received signals always conform to the published system specifications? In this month’s column we take a look at a specially designed receiver for analyzing GPS carrier phase and some of the interesting results that have been obtained. read more

Reminder: Leap Second This Weekend

June 29, 2012By

News courtesy of CANSPACE Listserv. Likely none of us needs a reminder as the upcoming leap second has been all over the news outlets for the past few days. But just to provide the details again, read this article. Presumably, all GPS receiver manufacturers have checked to make sure their receivers will handle the leap second properly. However, at least... read more

The Patent Brouhaha

June 28, 2012By

Two British technologists backed by the U.K. Ministry of Defense have filed patents on the future interoperable GPS and Galileo signal designs that severely disrupt modernization plans for both systems and suddenly, unexpectedly place receiver manufacturers in a highly uncertain and unfavorable situation. Some of the patents have been granted in the U.K. and in Europe, and applications are pending in U.S. patent court, with a ruling expected at any time. read more

Out in Front: State of the Industry

June 1, 2012By

It’s not been done before, so we’re going to do it now. In the September issue of this magazine will appear the very first State of the Industry report. On the GNSS industry, of course. It will cover such topics as the global economy and how it affects business in your sector. Customers’ availability of capital to invest is top-of-mind for most industry professionals, whether designers, manufacturers, integrators, suppliers/dealers, or end users. read more

The System: Commercial GPS in Combat

June 1, 2012By

Partnership Council Affords Insight, Drama By Alan Cameron This year’s GPS Partnership Council provided among other highlights a discussion of the tensions between commercial off-the-shelf (COTS) receiver systems used in tactical combat operations versus official military GPS user equipment (MGUE), and an enthralling warfighters’ panel that revealed much of those COTS/MGUE dilemmas. The event, held May 1–2 in El Segundo,... read more
