GPS FUNCTIONS
7.1
INTEGRATED 99 CHANNELS GPS RECEIVER
Digifly AIR features an extremely sensible, and state-of-the-art, 99 channels integrated GPS receiver.
7.2
GPS STATUS INFORMATION
The GPS status icon is located in the status bar, on the right lower part of the display (plotter screen) or on the
lower edge of the display (compass screen) and has different meanings:
1)
Fixed GPS icon = GPS FIX valid ( GPS position available)
2)
Blinking GPS icon = insufficient signal (GPS position NOT AVAILABLE)
7.3
GPS INFORMATION DISPLAY
This page shows in real time: Waypoint and symbol, Latitude,
Longitude, GPS direction (“TRK”), Ground speed (“GS” in km/h or
mph), GPS Altitude (“GPS-ALT” in mt or feet), Satellite’s number
(“SAT”), GPS Signal power (“hdp”).
In the status bar is visible also the flight recorder status and the
battery level
Pressing the key
(long pressure) it is possible to memorize a
Waypoint (“MARK” function), holding pressed the key
activates the
navigation function “HOME”.
7.4
LATITUDE & LONGITUDE COORDINATES OPTIONS
Three different kinds of coordinates are available:
DMS = grade, minute & second (dd° mm’ ss.s) (default)
DMM = grade & minute (dd° mm.mmm’)
UTM Universal Transverse Mercator (utm x, y, zone).
To set the coordinates DMM, DMS or UTM use the parameter (ADVANCED SETUP \ n. 23 CORD).
The coordinates latitude and longitude are referred to map datum WGS84.
7.5
GPS ALTITUDE
The GPS altitude is the height above the sea level accordingly to the satellite system (“AG”), it is visible in the
page GPS INFO.
7.6
GPS GROUND SPEED
The GPS ground speed is the glider speed related to the ground (“Gs”).
When a navigation is activated, the ground speed is visualized in reverse mode if the glider is moving away
from the waypoint.
