June 16, 2010By

I received some interesting e-mails and saw some web comments regarding my newsletter column a couple of weeks ago titled “What's Going to Happen When High-Accuracy GPS is Cheap?” The comments ranged from “I don’t believe it’s going to happen” to “We’d better adapt to the changes in technology.” read more

What’s Going to Happen When High-Accuracy GPS is Cheap?

June 3, 2010By

The GPS satellite launched into orbit last week wasn’t just any other GPS satellite. It was the first of a new generation of GPS satellites that are going to change the way surveying, engineering and construction data is collected and processed in the future. Its new features are going to profoundly transform surveying, engineering and construction. I’m not exaggerating. read more

The technical content, however, was still pretty good. In fact, I've included links to several videos I recorded at the ACSM/GITA conference. read more

LSAW Conference RTK Network Discussion Roundtable

March 18, 2010By

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
