Typical GPS status screen
This screen may help diagnose a NO FIX status. It provides infor-
mation for each for each tracked GPS satellite.
HDOP
The HDOP (Horizontal Dilution Of Position) value shown on screen
provides an indication of the positional accuracy. This will vary
depending upon the relative position of the GPS satellites and the
prevailing conditions.
An ideal figure is 1.0. which indicates optimum accuracy.
A consistently high value (6 or above) may be associated with
NO-FIX occurring frequently. Check that the GPS antennae has a
clear view of the entire sky and refer to the troubleshooting section
on
page 95.
