We welcomed our two guests to this 1 hour 35 minute discussion of their new book on GPS, its history, workings, uses, and more.  Remember, if you buy this book through Amazon using the OGLF portal and instructions in our archives, on the blog, and on TSS website as well as OGLF’s website, Amazon will contribute to The Space Show.  If you need further instructions on how to do this, please let me know.  During  our first segment, Richard started out by telling us about the book and why he wrote it, then his meeting up with Eric to be his co-author.  We talked about the early programs that led to GPS including the TRANSIT satellite system (NAVSAT), Naval Research Lab, plus other early tracking systems. We talked about timation and we also talked about the GPS systems in other countries such as Russia, Europe, India, and China.  Eric explained why the book goes as far back as the Sputnik era and at times even earlier.  Doug called in to ask about higher resolution GPS that could for example tell you traffic lane information.  As you will hear, that capability is pretty much available now but the resolution and solutions depend on the GPS product one buys or that is a consumer product.  We also talked about jamming and spoofing regarding the military GPS systems.  Monroe called with questions about GPS Open Source and amateur rocketry, plus signal loss at high speed and 4 g’s or more.  Also in this segment, we talked about the consumer GPS voice wanting to know if it was a real woman’s voice or a computer simulation.

In the second segment, we talked more with Monroe and also about mapping issues as an overlay for the raw GPS data.  Barry called regarding GPS and automatic flight control systems, then we talked some more with our guests regarding the early days leading up to the development of GPS.  Toward the end, our guests mentioned the GPS contribution to our economic GNP! Classified issues were discussed in general but since none of us had a security clearance, classified GPS was just mentioned in passing.  The website for the book is www.gpsdeclassified.com and I urge you to check it out

Please post your comments/questions on TSS blog above.  You can contact our two guests through me.
