    Re: leap seconds a navigational hazard, says expert

      I'm aware of that. And I've 
    intentionally ignored that, considering that the "simple" correction is only 
    one of many factors, which include operating and averaging some 4 atomic 
    clocks on each satellite, acquiring four satellites and computing the 3d 
    positioning of them all, doing the doppler frequency comparisons on them all, 
    and a lot more "donkey work" all of which has been accomplished long ago in 
    the software.
    The matter of the UTC/GPS time factor is, I would think, the LEAST of all the 
    things that can be going wrong with the GPS system. Something to consider if 
    one is guiding missiles perhaps, but as a practical matter for now...Just one 
    factor among many many others.
