Article: "Precise to a fault: How GPS revolutionized seismic research"

Here's a nice article that was published recently in EARTH magazine, entitled "Precise to a fault:  How GPS revolutionized seismic research," written by John Stenmark. He describes ways in which my colleagues and I have used GPS to study fault motions, beginning back in 1989 with the Loma Prieta earthquake. It is amazing to think back on how GPS technology has changed, and how many ideas and how much hard work by so many people it has taken to make it better along the way. Sometimes too much credit is given to one person for what really took a group or even a community. During the GPS L1C signal design work, I had the pleasure and honor to work with several of the prototype originators of GPS itself. They are commemorated in the GPS Hall-of-Fame at the Los Angeles Air Force Base. This EARTH article, which describes my application of GPS to earthquake research, also makes me reflect upon where we'd be without those true innovators of GPS. Their remarkable navigation & timing system prototype development was a truly great accomplishment.
