Acquire Current Position
The DAGR obtains current position by simply turning the
DAGR on with an open view of the sky. While acquiring
satellites, DAGR displays the SV Sky View page. After
satellites are acquired, DAGR automatically transitions to
the Present Position page with current position
coordinates shown. An indication of when the DAGR has
obtained current position is provided by:
– Position data fields of the Present Position page remain solid black text and
do not blink.
– On the SV Sky View page, solid black horizontal bars indicate satellites being
tracked and data is collected; and Navigating shows at the top of the display.
Acquire Current Position
The POS page set contains commonly used pages
and are described in the upcoming slides:
1.
Use the
key or
key to scroll pages.
Acquire Current Position
PRESENT POSITION PAGE: Displays present position coordinates, coordinate and grid
system, datum identifier, current operating mode, estimated horizontal error, figure of merit,
elevation, elevation reference, ground speed, track, estimated time error, time figure of
merit, time and date, MAGVAR, magnetic model year, and operator ID. Scroll the page
vertically to view all field data.

method, destination waypoint number
and name, azimuth, and range
information.
Acquire Current Position
IMAGE VIEWER PAGE: Displays, images or maps including current position (shown at
center of display), landmarks, map objects, and selected waypoints. The operator uses
zoom, pan, waypoint operations, and map selections to obtain desired view. The current
position map is automatically displayed when loaded.
Acquire Current Position

Waypoint Alerts
Definition: Alerts are made up of one or
more waypoints, and are used to notify the
operator is approaching or leaving a point,
line, or area of significance (e.g., radius
distance from a waypoint, defining a line
not to be crossed, mine field area).

it takes training to ensure continued
proficiency in the use of the device and
still requires each soldier to understand military
map and land navigation techniques.
