Via the APB Blog, the Coalition to Save Our GPS site offers news and information resources about the LightSquared wireless broadband proposal that may seriously disrupt the US GPS system. Lots of links to recent news, articles, white papers, FCC documents, and more. In particular, there’s a free PDF download of “GPS: The First Global Navigation System”, a book from Trimble that may be the best basic introduction to how GPS works that I’ve seen, and how it’s used; a bit technical in spots, but not overwhelmingly so.

I didn’t know there was a threat to the signal for GPS devices. I didn’t see a date for the post. Is the threat still a possibility now? I don’t have a GPS but could use one since for my job on occasion and for other times.

Yes, threat is still active. FCC doesn’t make a final decision until this summer.
