tracking satellite number 28. The satellite's elevation is 25 degrees above
the horizon and it's location is 44 degrees. It's SNR is 44, which is good.
The FIX numbers in the lower left corner of the screen show the quality of
fix. If the FIX is 9, then it's the best you can get. A FIX of 1 is the worst. The
DOPS display beneath the fix quality show you the "Dilution of Precision"
for the horizontal (HDOP), geometric (GDOP), position (PDOP), time
(TDOP), and vertical (VDOP). The GDOP is a combination of HDOP , VDOP ,
and TDOP . The smaller the DOP's value, the better. The receiver selects
satellites based on the GDOP value, therefore, it always tries to use sat-
ellites that have good DOP values. These depend on the azimuth and
elevation of the satellite, and any ground based obstructions.
Steering Screen (Group F and O)
The steering screen shows a pictorial view of your course and the dis-
tance to the side of the desired track to a waypoint. You must recall a
waypoint to use the steering screen.
Your present position is shown by a pointer near the center of the steering
screen as shown in group "O", above. It shows the direction you're head-
ing in relation to the waypoint. If you keep the pointer aimed at the top of
the display and centered in the middle, you'll reach the waypoint in the
shortest straight line.
The solid line extending from the pointer is the path you've taken. To travel
directly to a waypoint, try to keep the pointer on the center line. As you
approach the waypoint, a circle desends from the top of the steering screen.
This represents the waypoint.
Small numbers on the left side of the steering screen show the distance
from your present position to the recalled waypoint. If the numbers are
surrounded by a black box, then that is the distance past the waypoint.
The large numbers at the bottom of the screen show the distance you're
