The Position Display shows the position sensor in use, the
Latitude/Longitude position, and the EPE (Estimated Position Error).
GPS Sensors do not display an EPE. In this example, the In Use position
sensor is Loran 1, and the present Lat/Lon is 45°27.45’N, 122° 51.32’ W.
Position is displayed in degrees, minutes, and hundredths of a minute.
Seconds of Lat/Lon are not used. The EPE is 0.7 nm. If position has not
been calculated, the top line of the display reads, “Last Valid Position.”
