The Best and Final Look at the GPS 24+3 Configuration

Published February 17, 2010 By Eric Gakstatter Join the Discussion

I didn’t plan it this way, but my coverage of GPS 24+3 turned out to be a three-part series, with this column being part three. One reason it turned into a three-part series is because I’m learning more about it along the way, but its mostly because details weren’t released all at once.

Google Geospatial Technologist: “The End of GIS?”

Published February 16, 2010 By Eric Gakstatter Join the Discussion

I ran across an opinion piece entitle “The creative Destruction of GIS” by Ed Parsons, a Geospatial Technologist at Google, published online by GIS Development. I have to admit that when I first scanned the piece, my face crinkled up with the “whhhhaaaaat?” sort of look. For a common frame of reference, you might want […]

Published February 10, 2010 By Eric Gakstatter Join the Discussion

I received some mail about last week’s column on the Apple iPad announcement and I have also seen other comments on the web regarding the Apple iPad that I think are worth commenting on. Then, it’s just a matter of waiting to see how the market accepts the iPad once it starts shipping in Q2 of this […]

It’s a Mad, Mad, Maddenless World

Published February 9, 2010 By Don Jewell Join the Discussion

Call it Madden withdrawal. It’s bad enough that I just endured Super Bowl “XLIV” without the smooth and engaging color commentary of the iconic John Madden, the legendary Hall of Fame, Super Bowl (XI) winning coach and virtual football entrepreneur. This year I patently missed John’s pithy commentary and the distinctive timbre of his voice. Coach Madden’s broadcast career has continued for more than thirty years and his instantly recognizable voice always invokes the desire to watch a football game. I would watch any game he color-commentated even if I did not particularly care about the competitors. It just wasn’t the same Super Bowl this year without John Madden, but somehow I soldiered on.

GPS 24+3 Configuration: A Closer Look

Published February 3, 2010 By Eric Gakstatter Join the Discussion

In the few years I’ve been writing this column, very few subjects have warranted back-to-back newsletter coverage. The new GPS 24+3 configuration is one of them. The reason I’ve continued with this discussion is because it will significantly affect your GPS operations, especially if you’re using RTK or DGPS.

The Apple iPad Factor

Published February 2, 2010 By Eric Gakstatter Join the Discussion

Last month, I wrote about the PDA vs. Tablet war. The tablet computer has been around for a long time and struggled to gain widespread acceptance. I also wrote about how 2010 will be a decisive year for the tablet computer. I guess my timing was right: with the introduction of the Apple iPad last week, 2010 […]
