# IV. Information about GPS state
**The GPS fix after a long period of inactivity, or after an important change in geographical position, can take up to 10 minutes. It is recommended to be outdoor to ease the first GPS adjustment. We suggest you to turn ON your instrument a few minutes before taking-off.**
1. GPS state is shown with the bargraph on the top center of the screen:

A number indicates the number of synchronized satellites
