ing low signal levels due to poor coverage or installation problems.

The top line of the status page displays the receiver status and the current posi-
tion accuracy in DOP or EPE. The default setting is DOP.
The following functions may be displayed in the DOP/EPE field:
• dop— Dilution of Precision, a measure of the satellite geometry quality
and relative accuracy of your position, with 1 meaning good
geometry and 10 meaning poor.
• epe— Estimated Position Error, an overall measure of your positional
accuracy in feet or meters using signal and data quality, receiver
tracking status and DOP.
