    Re: Greenwich Conference: GPS military or civilian

    I was just reporting what went on at the conference. But with regard to your statements

    I think that needs to be qualified. Firstly, you may be correct that GPS has never been turned off globally. But I would suggest that a localised or regionalised shut down of GPS may well be possible. There were some fellas at the conference who seem to have ' been there' in sensitive areas at sensitive times who are pretty sure that is what took place. Of course, why should we believe them? But then, why should we believe you?

    2) GPS was designed to be used by both the military and the civil community from the get-go. Please see the first few paragraphs of the intro to my Innovation column in the April issue of GPS World:
    http://gpsworld.com/innovation-ground-based-augmentation/
    We (academics) used GPS even before the Reagan Administration's 1983 announcement and we even had unfettered access to the P-code throughout the 1980s.

    Richard Easton's recent GPS Declassified: From Smart Bombs to Smartphones is a trustworthy source for the details on GPS evolution.

    It was Richard Easton who gave a paper about the origins of the GPS system at the Greenwich conference two years ago. That there seems to be a difference in scholarly opinion on the reasons for the inception of the GPS system would appear to a valid fact....
