Wide Awake Bridging the Gap

March 30, 2010 - By

I gave this talk at the Munich Satellite Navigation Summit, in a concluding session titled “Bridging the Gap: A Journalistic View on Progress and Problems of GNSS.” __________ Before telling you what I came here to say today, I should really attempt to answer the question posed by our moderator:Is the world ready for new GNSS applications and services? If... read more

On the Edge: Lost Graves, Trail of Tears

March 27, 2010 - By

During the winter of 1838–39, the great Native American Cherokee Nation trekked across southern Illinois, in a forced removal by the U.S. government from their ancestral homeland in Tennessee. Harried, unequipped, and unsupported by their captors, thousands died on the Trail of Tears. Burial records were not kept, and burial locations remain lost to this day. Local history suggests that some Illinois settlers allowed the Cherokee to bury their dead on small plots of land adjacent to their own family cemeteries. One such plot, the Campground Presbyterian Church cemetery near Anna, Illinois, may contain unmarked Cherokee graves. read more

LSAW Conference RTK Network Discussion Roundtable

March 18, 2010 - By

A couple of weeks ago, I participated in a roundtable discussion at the Land Surveyors Association of Washington (LSAW) annual conference on the subject of RTK networks (RTN). I always enjoy listening to heavy RTK users on their thoughts, their procedures, and how they arrived at them. We danced around a number of subjects with one being the “RTN’s biggest flaw.” My first thought was the communications link, but... read more

The System: New Kid on the Block: IIF Readied

March 1, 2010 - By

The first Block IIF satellite destined for orbit arrived at the Navstar Processing Facility at Cape Canaveral, Florida, aboard an Air Force C-17 cargo aircraft on February 12. It is now undergoing preparations for its launch this spring on a Delta IV rocket. Block IIF will enhance GPS performance by reportedly providing twice the navigational accuracy of heritage satellites, more robust signals for commercial aviation and search-and-rescue, and greater resistance to jamming in hostile environments. Plus: GLONASS, Beidou, Galileo, 24+3 FAQ, and AEP 5.5C software update. read more

Expert Advice: Are We There Yet?

March 1, 2010 - By

At the start of a new decade, let’s examine the state of the GNSS consumer market and technology. In the December 2009 issue of GPS World, I described the developments that put GPS in cell phones over the last decade. That technology revolution has brought GPS a very long way. Having come this far, we can ask that most famous of all navigation questions: Are we there yet? read more

Out in Front: Apply the Seat of the Pants

March 1, 2010 - By

Not “fly by,” but “apply.” As in W. Somerset Maugham’s advice to aspiring young writers: Apply the seat of the pants to the seat of the chair. Get grounded. Confront the blank page, the typewriter, or the less preferable modern equipments (because instant electronics short-circuit orderly brain function) for a period of silence and contemplation. Above all, think. Then, and only then, communicate. read more
