Position Screens
Position screens #1 and #2 display your present position us-
ing the coordinate systems that you have selected. This screen
shows all of the basic position, time and satellite information.
Additionally, on Position screen #1, current navigation infor-
mation is shown in the bottom half of the screen.
For the sake of comparison, Position screen #2 provides the
coordinates of your present position both in the selected pri-
mary coordinate system and map datum, and in the selected
secondary coordinate system and map datum.
Position screen #1 contains the following information, from
top to bottom:
-
Coordinates and elevation of your current position: Dis-
plays your current position in the chosen coordinate sys-
tem. Also displays the elevation of the current position. If
MobileMapper Pro is not computing position fixes, the last
computed position is displayed.
-
GPS Satellite Status: Provides information on the current
status of the GPS receiver portion of the MobileMapper
Pro (see table below).
