This Navigation Blog, The Nog, is focused on navigation issues, methods and analysis. The original Nog was hosted by my company, Analytical Graphics Inc. They've since discontinued that blog, but I'm still writing about navigation related issues. I'll discuss general navigation issues here, as well as how to use different tools to analyze navigation problems. I'll focus mainly on radio-navigation topics (GPS, Galileo, GNSS).
I'm Ted Driver, feel free to contact me with ideas and comments.
Thanks for visiting!
