Position Page
The second page in the GPS 12’s primary page
sequence is the Position Page. This page shows you
where you are, what direction you’re heading, and how
fast you’re going, and it’s most useful when you are trav-
eling without an active destination waypoint. The graph-
ic heading display at the top of the page indicates the
direction you’re heading (track) while you’re moving.
Directly below this display are the track, speed, and
trip odometer (default) fields. Track is the compass
direction representing your course over the ground, or
the direction you’re moving. The lower left-hand cor-
ner of the page shows your current latitude and longi-
tude in degrees and minutes. The GPS 12 uses this
basic information to mark exact positions as waypoints,
which help guide you from one place to another. The
lower right-hand corner of the page contains the alti-
tude field (default). Below that field is a 12- or 24-hour
clock.
Both the trip odometer and the altitude fields are
user selectable, and both offer a trip odometer, trip
timer, and elapsed time. This way, you can always be
sure of viewing this information regardless of the
option you’ve selected for the other user-selectable
field.
The following user-selectable options are available
on the Position Page:
Trip Odometer (TRIP)—
total distance
traveled since last reset.
Trip Timer (TTIME)—
total (cumulative)
time in which a ground speed has been
maintained since last reset.
Elapsed Time (ELPSD)—
total time in
hours and minutes since last reset.
Average Speed (AVSPD)—
average speed
traveled since last reset.
Maximum Speed (MXSPD)—
maximum
speed traveled since last reset.
Altitude (ALT)—
vertical distance above
mean sea level.

The speed and track dis-
played on the Position
Page may fluctuate at
slow speeds (or when
y o u ’ re standing still)
because of position errors
caused by DOD-imposed
Selective Availability.
