    Re: Susceptibility of GPS to CME, Rationale for CN?

    I must be +4.   I do not own a boat and the only cnav I have done is from my backyard with an artificial horizon. I can still remember the thrill when I  made my first noon observation, watching the sun climb, hang and then start to descend. It was even more exciting when I performed a long by chron. To put it simply I had proved to myself that astro worked!
