GPS Settings
This screen allows you to view and change the settings that affect
how MapSight operates with GPS satellites.
GPS Position Dilution of Precision (PDOP) value is a measure of the
overall accuracy of the current position. The lower this value is
then the more accurate your GPS position is likely to be. A value of
100.0 is displayed on the targeting preview screen when PDOP
cannot be calculated.
Maximum PDOP
value slider
If the current PDOP reading is above the GPS
Maximum PDOP
setting, a warning will be shown on the capture preview screen by
the display of an orange border around the PDOP reading. The
Maximum PDOP
setting can be adjusted by sliding the level to the
left or right to lower or increase the
Maximum PDOP
. The default
Maximum PDOP
value is 6. A lower value may result in more
accurate the fix, but this may increase the time to get a fix. A
higher Maximum PDOP may reduce the time to get a fix, but will
likely decrease the accuracy of the fix.
Enforce Maximum PDOP
checkbox
When
Enforce Maximum PDOP
is enabled, data capture will not be
possible if the GPS readings exceed the
Maximum PDOP
. If
Enforce
Maximum PDOP
is unchecked, then an orange border will still show
around the on-screen PDOP value but positional readings can be
taken if the maximum is exceeded.
WARNING!
If
Enforce Maximum PDOP
is unchecked,
positional detail of MapSight and target readings is may be
less accurate.
GPS Mask Angle
value slider
The GPS Mask Angle default is set to 15
o
. Even if they are visible,
satellites that are at a lower elevation than the GPS mask angle will
not be used to calculate position. The
GPS Mask Angle
can be
adjusted by moving the slider bar left or right.
