6.6 GPS Setup

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: Navigation Status Window

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.
