Beneath the circular graph are the bar graphs, one for each satellite in
view. Since the unit has twelve channels, it can dedicate one channel
per visible satellite. The taller the bar on the graph, the better the unit
is receiving the signals from the satellite.
The Position Error box (sometimes called EPE for "Estimated Position
Error") is shown in the bottom left corner of the screen. This is the ex-
pected error from a benchmark location. In other words, if the Position
Error shows 50 feet, then the position shown by the unit is estimated to
be within 50 feet of the actual location. This also gives you an indicator
of the fix quality the unit currently has. The smaller the position error
number, the better (and more accurate) the fix is. If the position error
flashes dashes, then the unit hasn't locked onto the satellites, and the
number shown isn't valid.
