Yesterday I conducted a webinar titled “A Closer Look at L5: The Future of High-Precision GNSS.” Preparing for it was quite interesting, so I thought I’d share some of the slides I produced (and had produced) for the webinar. I think you’ll find them interesting. The webinar ...
Read More →In light of this weeks webinar, A Closer Look at L5: The Future of High-Precision GNSS, and spurred by an email from a reader about how to sift through all the GPS/GNSS receiver choices, following are my thoughts if you’re looking to purchase an RTK receiver today. First of all, an email from ...
Read More →This week I’m following up on my article from a couple of weeks ago about the potential effects of LightSquared’s plans. As a user of high-precision GPS receivers (particularly GPS L1 sub-meter, but also dual-frequency), you should be particularly concerned about this issue. I’ll t...
Read More →Last week, I conducted a webinar along with Dr. Michael Whitehead titled “SBAS, DGPS or Post-processing? Which Should You Use?” It was one of the best webinars I’ve conducted to date. More than 600 people registered. We barely squeezed it into 65 minutes and could have kept going f...

Galileo has been discussed off and on for well over a decade and was a hot topic for a number of years. In fact, back around 2001, the U.S. really d...
Read More →If you’ve been around GPS mapping for any length of time, I’m sure you’ve heard of post-processing, and you may have even experienced it yourself. If you used GPS for mapping in the ’90s, you almost certainly post-processed your data. In fact, sometimes you had to pay for access to GPS b...
Read More →With this being my last column in 2010, I’m going to look back at the five significant GPS/GNSS events in 2010 that affected the surveying, mapping, engineering, construction, and natural resource users. Each of these had, or could’ve had, a significant effect on your GPS activities. The...
Read More →In my last column, I presented the poll results from my November 16 webinar “A Buyer’s Guide to GPS/GIS Mapping Equipment.” I’ve conducted many webinars over the years, and the audiences have been comprised of hundreds (if not thousands) of participants who have the ability t...
