Checking
GPS Signal
Strength
The unit shows the GPS signal strength screen in
the GPS Sensor function. Make it a habit to check
this screen to make sure that the unit is properly
tracking visible satellites before you fly. The Apollo
SL50/60 requires signals from at least four satellites
to calculate a 3D position fix (Lat/Lon and GPS
altitude). More details are available in the GPS
Sensor part of the System section of this manual,
see page 80.
