NotUsed?Prev?9
This menu item is the number of satellites that are
currently being tracked by the GPS engine, have
an ephemeris, are healthy, and are above the
elevation mask.
Above?Ele????9
This menu item indicates how many satellites are
above the current elevation mask setting. An
elevation mask is used to ignore satellites that are
low on the horizon, but still usable, as they will
have more significant tropospheric refraction
errors. A satellite below the elevation mask is
ignored from the position solution. See Section
4.9.3 for further details on setting the mask angle.
Diff?Corr????8
This menu item indicates the number of satellites
that have valid differential correctors in use. The
number of correctors present will depend on the
information broadcast by the differential service
in use. There will not be correction information
for satellites tracked by the remote receiver but
not the base station. As a consequence, these
satellites are not used in the position calculation.
No?Diff?Corr?0
This menu item indicates the number of satellites
that have no differential correctors present and are
ignored in the position solution, until correction
information becomes available.
