GPS Constellation Management: Playing Not to Lose Posted on 22 Oct 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

In sports, there is a phenomenon that sometimes occurs when a team is leading towards the end of a game. It’s called “playing not to lose.” The reason you are seeing high HDOP warnings from the NAVCEN and GPS “brownouts” during the day when RTK (GPS-only) isn’t working is because the GPS satellite constellation is sub-optimal. The current design of the GPS constellation is not focused on “playing to win”, but rather “playing not to lose.” Read more»

“What Can GLONASS, GPS L2C, and GPS L5 Do for You?” Webinar Q&A Follow-up Posted on 06 Oct 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

As I’ve been accustomed to doing, this newsletter addresses the questions you submitted during the Sept. 15 webinar entitled “What Can GLONASS, GPS L2C, and GPS L5 Do for You?”. There were some great questions during the webinar, and a lot of them. There were so many, in fact, that I’m going to break them up into a couple of different newsletter issues. Also, I need to update you on my trip to ION GNSS a couple of weeks ago. I might mix up the next newsletter with more Q&A as well as the ION GNSS update. Read more»

ION GNSS/CGSIC annual conference Posted on 25 Sep 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

I realize the GIS world doesn’t revolve around GPS but I’m going to spend some space on it this month. Currently, I’m in Savannah, Georgia at the annual ION GNSS/CGSIC conference. Read more»

Navigating the World of GNSS Posted on 09 Sep 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

The increasing number of Global Navigation Satellite Systems means more choices — and more confusion — for the user. Knowing the capabilities and schedules of each can help you make more informed purchasing decisions, including when (and when not) to upgrade existing equipment. Read more»

ION GNSS Conference Peers into the Future of Surveying Posted on 01 Sep 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

The Institute of Navigation’s Global Navigation Satellite Systems (ION GNSS) conference is one of my two favorite industry events of the year; the other being the ESRI conference. At ESRI, I mix it up with GPS technology users, listen to what they are doing and what they want to do with the technology. At ION, I listen to GNSS designers and researchers. Read more»

ESRI Conference and SVN-49 Troubles Posted on 29 Jul 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

I had a great visit at the ESRI User Conference earlier this month. If you recall last year, I wrote: “As much as surveyors, engineers, and constructors may not appreciate geographic information systems (GIS) technology, at some point everyone should attend at least the ESRI Survey/Engineering Summit and the first couple of days of the ESRI User Conference held every summer in San Diego, California. This is not a GIS sales pitch. It's a networking sales pitch. When other conferences are struggling to maintain attendance levels, the ESRI conferences seemingly never fail to grow in attendance. This year, it attracted some 15,000 people from 120 countries. That means gobs of GIS people, and also gobs of surveyors and engineers.” The statement rang true this year too. Even in today’s economy where conferences are severely impacted or even cancelled due to travel budget cuts, the ESRI User conference still attracted ~11,000 people this month. Read more»

GPS Receivers for GIS Data Collection Posted on 22 Jun 2009 in the Newsletter Editorials & Opinions & Survey & Survey Scene categories.

In my column earlier this month, I discussed the use of consumer GPS receivers for GIS data collection. Remember the analogy I used?a Volkswagen Beetle wasn?t designed to run in a Formula One race? This column is going to focus on the Formula One cars, not the Volkswagen Beetles. In other words, it will focus on the GPS receivers on the market that are designed for GIS data collection. I will refer to them as GPS/GIS receivers. Read more»
