GPS SIGNAL AND BATTERY LIFE (Leonardo Models)
With the GPS power saving mode set to “STD” (ADVANCED SETUP \ n. 7 POWE). The
integrated GPS receiver in the Digifly Leonardo consumes 90% of the total current of
the instrument and consumption depends on the strength of the satellite reception.
During outdoor usage with full sky visibility (3 bars) and with at least 5 satellites (SAT)
you can achieve 30 hours of battery life. During indoor use, with poor sky visibility (2
bars) the GPS receiver switches to high power mode and consumes up to two times
more current. As a result of poor satellite reception, the expected battery life can be
reduced to 15 hours or even less.

GPS INFORMATION DISPLAY
To view the GPS information display, press the
key (long
press).
On this page you can read in real time: Waypoint name and
symbol, Latitude, Longitude, GPS Direction (“TRK”), Ground
Speed (“GS” in km/h), GPS Altitude (“GPS-ALT” in mt), Satellite
Number (“SAT”) and the strength of the GPS Signal (“hdp”), and
Battery Voltage (“VBAT”).
7.6
LATITUDE & LONGITUDE COORDINATES
Latitude and Longitude are referenced with respect to the WGS84 Map Datum.
7.7
GPS ALTITUDE
GPS Altitude is the altitude above sea level (“AG” icon).
7.8
GROUND SPEED GPS
Ground Speed is the speed over the ground (“Gs” icon).
7.9
GPS DIRECTION (TRK)
GPS Direction (“TRK”) is the direction of movement relative to the ground.
7.10
GROUND EFFICIENCY (GLIDE RATIO)
When you select the “air speed” or “ground speed”, on the
left side of this data field is displayed the ground efficiency .
