Out in Front: Of Rats, the Mind, World Series, and Truth

November 1, 2014By

My colleague Janice Partyka wrote a provocative blog in the Wireless/LBS Insider on discovery of the brain’s inner GPS, which won three scientists a Nobel Prize for medicine. The piece struck me so forcefully in the hippocampus, locus of my location sensibility, that I was tempted to place it here verbatim. That would not justify me, however, in drawing my pay,... read more

Out in Front: Curing Cancer

October 1, 2014By
source:  global.

As in, “It’s not like you’re curing cancer,” a refrain I hear sometimes when I get a bit over-inflated on GPS/GNSS and the wonders they can do in many fields of human endeavor. The intent of that remark is to remind me that on the one hand, there is technology. On the other hand, there is life, and there is... read more

Out in Front: 25 Years Young

September 1, 2014By

When I was a young man, the moment seemed like all there was, all there needed to be. Why plan? Why reflect? The days were just packed. Once I turned 25 — or somewhere around there — intimations dawning of my own mortality, I began to look both forward and back. It seemed like a good idea, perhaps even an... read more

Out in Front: The State of Our Union

JEFF FEHLBERG, winner of the drawing for a Trimble Juno T41, grand prize in the 2013 State of the Industry Survey. You, too, can be this lucky!

Like Olympic athletes, doctors without borders, and magicians, members of the GNSS community constitute an informal international group that gathers periodically, in different centers around the world, to share knowledge and advance their craft. It is due and fitting, perhaps even necessary, that we also try to summarize or collect our views about ourselves, our field, and our future. The... read more

Out in Front: Epic Fail

July 1, 2014By

Sometimes the patient has to get sick in order to get better. The eruption of a malady leads to identification of an underlying condition; appropriate treatment can then be devised to cure the body of its ills. Sound like House, M.D.? As a variant on this plot line, the patient can know full well what is wrong deep down inside,... read more

Letters: Galileo Sync, GLONASS Scoop, an Open Letter

June 23, 2014By

June Cover Story In the June issue’s cover story, “Interchangeability Accomplished,” is a paragraph headed, “Satellite Intersystem Biases,” which appears to assert that Galileo System Time (GST) is 3 seconds ahead of UTC. However, in the version of the Galileo Signal In Space Interface Control Document posted at: http://ec.europa.eu/enterprise/policies/satnav/galileo/files/galileo-os-sis-icd-issue1-revision1_en.pdf, paragraph 5.1.2 appears to indicate that Galileo System Time (GST) was synchronized, at... read more

Letters to the Editor: Of Services, Commercial and Non

Veripos ground receiver station network.

In a comment posted to GPS World’s website on Tony Murfin’s recent column, “Hexagon’s Acquisition of Veripos: Why Did This Go Down?”, Craig Roberts of Australia wrote: Tony, I do take issue with the suggestion that the International GNSS Service (IGS) is somehow inferior and not reliable. I understand that Veripos is a commercial service designed for specific markets, but... read more

Out in Front: How Much Farther?

May 1, 2014By

For some years now, we have been talking about GNSS interoperability. The concept has received so much careful attention at conferences, in R&D laboratories, in international working group forums, and behind closed high-level government and military doors, that one might understandably conclude that we have talked interoperability into existence. Not quite. Not nearly. Not by the farthest, if measuring into... read more
