In the wake of last month’s Expert Advice column on eLoran — “The Low Cost of Protecting America” by Dana Goward of the Resilient Navigation and Timing Foundation —  come several positive comments and encouraging developments. Rather than rehearse all the arguments why we should care about this, I’ll repeat the one word that I heard most often in GNSS... read more

China’s BeiDou system claimed a user range error (URE) of 2.5 meters zero age of data (ZAOD) 95% recently.  The parallel GPS specifications commit to 6 meters 95% ZAOD and 7.8 meters 95% all AODs.  Does this mean that BeiDou is more accurate than GPS? Not so fast. In late December, director Ran Chengqi of China’s Satellite Navigation System Management... read more

Record Number of Automakers at International CES

January 22, 2014By

It’s a daunting task — trying to find the big location story in a maze of 150,000 attendees and thousands of exhibitors at the International Consumer Electronics Show in Las Vegas. Aside from every automaker touting their connected vehicle efforts, the big deal this year at CES is wearable technology (last year it was 3D printing? Yawn). Despite sore feet from walking football-field lengths of booths, CES is still a cool show, blaring stereos, walls of TV screens, robots…and connected cars. read more

Review: Putting the Mountain-Tough Yuma 2 through Its Paces

January 8, 2014By

My original review of the first Yuma rugged tablet from Trimble MCS (Mobile Computing Solutions) was penned in August of 2011. My original plan was to have the review of the new Yuma 2 ready to go exactly two years later. But, as we all know, man plans and God laughs. Actually, the problem, I must admit, is a bit more personal in nature; you see, I have been enjoying the Yuma 2 to such a degree that it was difficult to write about it because then I have to send it back. I have been selfish too long — read on for the review of the new Trimble Yuma 2 rugged tablet computer that is perfect for fieldwork, especially fieldwork involving GPS and GIS applications. read more

January 1, 2014By

By Dana A. Goward Highly precise and free for use by anyone with an inexpensive receiver, GPS and other GNSS are great. Their navigation and timing signals have been incorporated into nearly every aspect of modern life, from synchronizing power grids to financial systems, the Internet, telecommunications, and transportation. The U.S. Department of Homeland Security estimates that these signals are... read more
