GPS set up page provides you with information and the status of the tracked
navigation satellites for a SeaTalk GPS. It also enables you to SET UP a SeaTalk
Differential GPS, by manually retuning it to a different differential beacon.
The GPS Navigation Status pop-up window (shown in Figure 6-4) provides,
for each tracked satellite, the satellite number, a graphical signal strength bar
and its current usage status. HDOP and satellite Fix Status are also displayed.
Data for up to 12 satellites are shown.

Figure 6-4:
Positional accuracy is dependent upon certain parameters; in particular for
GPS, the azimuth and elevation angles are used in a triangulation process to
calculate position. HDOP (Horizontal Dilution Of Position) is a measure of
this accuracy; a higher figure signifies greater error. In ideal circumstances,
the figure should be in the region of 1.0. The Fix Status can indicate:
• FIX, where a satellite fix has been acquired.
• D-FIX, where a differential beacon fix has been acquired.
• SD-FIX, where a satellite differential fix has been acquired.
• NO FIX, where no fix can be acquired.
