Down in the Flood with GPS

March 31, 2015By

Surveyors, prepare to get your feet wet. Global warming is about to hit you in the job list. By 2050, a majority of U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year. This according to a December report in Earth's Future, a journal of the American Geophysical Union. read more

What Exactly Is GPS NMEA Data?

February 4, 2015By

You may have heard about “NMEA data” with respect to GPS. NMEA existed well before GPS was invented, and today is a standard supported by all GPS manufacturers. NMEA gives equipment users the ability to mix and match hardware and software, and makes it easier for software developers to write software for a wide variety of GPS receivers. What makes NMEA confusing is that there are quite a few NMEA messages, not just one. This month, I break down the mysterious NMEA code. read more

First of all, on behalf of all of us here at GPS World magazine, allow me to welcome you to 2015. We wish you a healthy and prosperous new year! I’d like to start out the new year stating the obvious for some of you, maybe most of you…perhaps all of you: GNSS is the new GPS. In the high-precision... read more

What Happened to Piksi, the $995 RTK GNSS Receiver on Kickstarter?

Piksi

A little more than a year ago, Swift Navigation started a Kickstarter campaign for a $995 RTK GNSS receiver named Piksi. The goal was to raise $14,000 for the project. By the time the Kickstarter campaign was ended, Swift raised $166,097 from 303 backers. I wrote an article about the Swift’s Kickstarter campaign in September 2013, a few days before... read more

Trimble Dimensions Provides Focus on Range of Satellite-Based Correction Services

November 5, 2014By

With more than 4,000 attendees, this year’s Trimble Dimensions User Conference was the largest ever and, I must say, a well-organized event chock full of technical content — enough to squelch the most intense geospatial hunger pangs you might have. One could write a book on all the technology and market segments that Trimble is pursuing and offering solutions for. In... read more

Discussion Panel Members:
High Precision GNSS - What will it Look Like in 2020?

In September, I attended the Institute of Navigation (ION) GNSS+ conference in Tampa, Florida. The ION GNSS+ conference is a gathering where many of the GNSS scientists from around the world come to share their successes, trials and tribulations. It gives one a view into the future of where GNSS positioning might go. Granted, most of the ideas and concepts... read more

All Eyes on Galileo

September 3, 2014By

The year 2014 is most certainly the Year of Galileo. After rising up from near elimination in 2008 due to much confusion about how to fund it, the European Union, that same year, decided to allocate 3.4 billion euros to fund the ground infrastructure and the initial satellites. Unlike the U.S. GPS and Russian GLONASS systems, Galileo is civilian-funded as opposed to being funded primarily from defense budgets, which makes it politically much more difficult to gain funding. But, they did it. That was six years ago. read more
