It is basically what most people call "position hold mode" where the receiver
has known (and accurate) fixed coordinates. With lat/lon/alt known, it can
solve for time with just one satellite visible. Or, if more than one sat is
visible, its time solutions can be more accurate because noise in the
lat/lon/alt calculations won't affect the time solutions. The gotcha is any
error in your fixed position coordinates directly contribute to time errors
(figure 1 nanosecond per foot of error).
