Consult your receiver’s documentation for more information.
Position
The Position card displays your current position as well as your
course and speed information if you are moving. The Position card
will display one of three coordinates: WGS84 latitude, longitude,
height; Local latitude, longitude, height; or Grid north, east,
elevation.
Solution : (see the Receiver card on Page R-168.)
Latitude/Longitude/Height: or North/ East/ Elevation :
displays the location of the receiver.
Heading : displays your course over ground if you are
moving. If your coordinate display is geodetic, this
heading is with respect to geodetic north. If your
coordinate display is grid, then this heading is with
respect to grid north.
Speed : displays your horizontal speed over ground if you
are moving.
WGS84 : is where you set the position display to show
WGS84 latitude, longitude, and height. This option is
always available.
Local LLh : is where you set the position display to show
Local latitude, longitude, and height. This option is only available
when you have a coordinate system selected and solved.
Note: Local LLh numbers make sense when in mapping plane mode.
When using Ground – TDS Localization mode, you should not use
Local LLh display.
Grid
: is where you set the position display to show Grid north, east,
and elevation. This option is only available when you have a
coordinate system selected and solved.
