DAGR
Defense Advanced GPS Receiver
Navigating through
known points
Instructors: Sgt Foley, Sgt Leier
3 Things you must know
• Know where you are.
• Know where you are going.
• Know how you will get there.
Objectives
•
•
•
•
•
Find your Location
Calibrate Compass
Enter waypoint information
Create a route using waypoints
Follow route using Navigation and map
screens
Finding Your Position
• The first screen shown on the DAGR is the
Satellite Sky View. Press MENU choose Select
Op Mode choose Continuous.
• Once the DAGR has a fix on it’s position the
status on the top of the screen will change from
Acquiring SV’s to Navigating.
• Pressing the POS PAGE button once will display
the PRESENT POSITION screen. This shows
the current grid coordinates for the DAGR.
Internal Compass
• From Main Menu go to Display Setup then
choose Internal Compass
• On the Internal Compass screen press
Menu then choose Calibrate
• Follow instructions to rotate the DAGR
until the calibration is complete
Determining Waypoints
• Waypoints are just checkpoints along a route. These
could be intersections, turns in the route, danger
crossings or just checkpoints to stay on the path.
• The waypoint is written as the Grid Zone Designation
and the 10 digit grid such as 14T NT 1234509876.
Enter Waypoints
• From Main Menu choose
WP/Route/Alerts then choose
Waypoints (WPs).
• Press ENTER on the first empty
slot then ENTER again. This is
the configuration page for that
waypoint.
• Press ENTER on the name to
rename the waypoint then down
arrow to select the coordinates
and press ENTER to input the
grid location for that waypoint.

14U NU 06158E 22559N
14U NU 06024E 23187N
14U NU 05929E 22744N
14U NU 05239E 23025N
As an 8 digit grid the first point would be
written as: NU05942236.
“14U” is the Grid Zone Designation.
Create a Route
• From MAIN MENU choose
WP/Route/Alerts then
choose Routes
• Hit ENTER on the first
empty slot then change the
name to something relevant
• ARROW DOWN to the
waypoints portion of the
screen and at each leg
press enter to choose the
order of the waypoints
Enter a Route
Navigating
• From the ROUTES screen highlight the route then press MENU
and choose NAVIGATE ROUTE.
•The DAGR now shows the NAV
POINTER screen.
POS PAGE button
• Pressing the POS
PAGE button will
now cycle through
the different status
pages which are
• 1: PRESENT
POSITION
• 2: SITUATIONAL
AWARENESS
• 3: NAV POINTER
• 4: IMAGE VIEWER
• 5: SATELLITE SKY
VIEW
Present Position
Displays current poisition in chosen cordinate
system, estimated error and elevation
Arrowing down shows ground speed, travelling
azimuth, current time and date
Arrowing further shows magnetic variance
between compass and grid north and your
operator identification
Situational Awareness
This screen shows a basic map
with range rings to show your
relative proximity to nearby
waypoints and posted danger
areas
On this screen you can also
zoom in or out using the F1 IN
button or F2 OUT button, while
doing this pay attention to the
scale in the lower right corner
showing the distance that each
range ring represents
In the lower left you also see
your current speed and
heading while travelling
Nav Pointer
This screen displays a moving
compass that is based off the
internal compass. It is
important to remember that
this compass is not accurate if
the DAGR is not held level.
The upper right corner shows
either the waypoint you are
guiding too or the leg of the
route you are currently
following. Underneath that is
the direction and distance to
that point.
Image Viewer
This screen is only
useful once you have
maps of the Area of
Operation loaded into
the DAGR.
Maps are loaded using
a laptop computer and
show important terrain
features such as rivers,
roads and major
elevation changes to
help in navigation.
Satellite Sky View
Displays what satellites are in view
at the current date and time.
The top of the page displays the
current tracking status or which will
show Acquiring SVs… (while the
DAGR is initially receiving satellite
data), Navigating (once the DAGR
has determined your position) or
Standyby Mode (when the DAGR
is not actively searching for a
signal.
The length of the bars on the left
show the relative signal strength
from each satellite.
