of their signals by looking at each satellite’s Signal-to-Noise Ratio (SNR). The higher the ratio, the
better the quality.
Although the U.S. government identifies WAAS satellites by their pseudo random number (PRN)—a
three-digit number ranging from 120 to 138—the
6000i
identifies them by two-digit numbers
ranging from 33 to 51. For example, the satellite for the Atlantic Operating Region (AOR) is PRN 122,
which the
6000i
displays as 35. See Table 8 below for the identification numbers for WAAS satellites
that may be displayed on the screen.
Checking DGPS status
If you have connected a SC-104 compatible beacon receiver, press
DGPS INFO
from the
GPS
POSITION
screen to display the
DGPS STATUS
screen. Check for low noise levels and mid-range SNR
readings.
Installation-test checklist
To check-out the
6000i
system after installation:
1. Turn on the
6000i
, then check for the presence of GPS and WAAS.
2. Review the functions: With a chart cartridge inserted
,
check that the
CHART
screen is
displayed. (Be sure to close the chart door securely.)
3. Confirm that the
GPS RECEIVER
options are at the desired setting
.
Press the

menu key to display the
RECEIVER OPTIONS
screen. If necessary, use the cursor pad to
move the arrow, press
EDIT
, change to the desired setting, then
press
ENTER
.
