This query returns the number of satellites that the almanac predicts should
be visible, given date, time, and location (if any of these are incorrect, the
prediction will be incorrect).
Response
Number of satellites predicted visible.
Theory
Satellites must be in view to be tracked. At least four satellites must be in view,
and tracked, to determine the position in position survey operation. Only one
satellite must be in view, and tracked, to maintain operation of the reference
oscillator locked to GPS when in position hold operation.
