Garmin GNC 300 - Manual (Page 26)

The GNC 300’s satellite status page provides satellite information to monitor
GPS coverage and receiver performance. This is helpful when you may be experienc-
ing low signal levels due to poor coverage or installation problems.
To view the satellite status page:
1. Press
N
and rotate
O
until the satellite status page appears.
The top line of the status page displays the receiver status and the current DOP or
EPE. Dilution of precision (DOP) is a measure of the satellite geometry quality and
relative accuracy of your position, with 1 meaning good geometry and 10 meaning
poor. Estimated position error (EPE) is an overall measure of your positional accuracy
in feet or meters using signal and data quality, receiver tracking status and DOP.
To view information on DOP/EPE:
1. Press
N
and rotate
O
to display the satellite status page.
2. If the desired field (EPE or DOP) is not displayed, press
C
twice.
3. Use
K
to change between ‘epe’ and ‘dop’. Press
C
to finish. 16
