    ---------
    Your GPS is correct!
    ---------
    >dist = 6366.7*Arccos(sin(lata)*sin(latb)+cos(lata)*cos(latb)*cos(lonb-lona))
            ??????
            ??????
    The equation above is incorrrect.
    --------
    The above equation should read for the Great Circle Distance between Points
    A and B
    located as;
            A at location (Lat_A, Lon_A) and B at  (Lat_B, Lon_B)
    Distance A to B = 60*ArcCos[Sin(Lat_A)*Sin(Lat_B) + Cos(Lat_A)*Cos(Lat_B) *
    Cos(Lon_A -Lon_B)]
    The result is in nautical miles.
    --------
