4.8.14 GPS status

In the main menu the GPS provides a detailed view of the GPS status,the current position dilution of

precision (pdop) value ,and the current GPS coordinates of the pilot.

Figure 4.36: Satellite status

Figure

4.36

illustrates the GPS satellite reception page. In this example the GPS shows that 8 satellites

are visible, and all 8 are being used to provide the position x. Each bar shows the signal strength for

each individual satellite. A lled bar indicates the GPS has a lock on that satellite. The position dilution

of precision (pdop) shown gives an indication of how reliable the GPS data is at the moment. The lower

the pdop value the more accurate the position x. Values bellow 2.5 are fairly accurate. If the GPS is

switched on in a location where no satellites are visible (indoors for example) it will go into wide search

mode. If this occurs, going outdoors again will make the GPS take an increased amount of time to pick up

satellite signals. If this occurs pushing ENTER on the GPS menu item will reveal the Reset GPS option,

changing it to yes will make the GPS reset the GPS status and start a new search (see Figure

4.37

). So

if you notice GPS is taking abnormally long to get a x (over 2 minutes) a gps reset will probably get it

locked quicker.
