The SatelliteInfo example shows how the available satellites at the user’s current position and marks the satellites currently contributing to the GPS fix as pink.
Key Qt Positioning 类被用于此范例：
The example displays the signal strength of all satellites in view. Any satellite that is currently used to calculate the GPS fix has been marked pink. The number at the bottom of each signal bar is the individual satellite identifier.
The application operates in three different modes:
Application mode
描述
running
The application continuously queries the system for satellite updates. When new data is available it will be displayed.
stopped
The application stops updating the satellite information.
single

If the platform does not provide satellite information the application automatically switches into a demo mode whereby it continuously switches between predefined sets of satellite data.
