Figure 4.33: Airspace Settings Example

4.7.14 GPS status

In the main menu the GPS SD 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 4.34: Satellite status

Figure

4.34

illustrates the GPS satellite reception page. In this example the GPS SD 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 SD 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 SD 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 SD 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 SD reset the GPS status and start a new search (see Figure

4.35

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

probably get it locked quicker.
