●
Longitude component of position in degrees, minutes and fraction of minutes
●
Latitude component of position in degrees, minutes and fraction of minutes
●
Z: Altitude in meters above sea level
●
Velocity: Speed over ground (vector of all 3 dimensions)
●
Direction: True track over ground
●
Distance: Integration of speed for getting the displacement (Only speed levels above 0.5 km/h
are used to calculate the distance)
●
Used sat.: Numbers of satellites used for calculation of position and speed
●
Current sec: Seconds since midnight (UTC)
●
GPS fix quality: To recognize in which mode the receiver is (Standalone, DGPS, RTK)
●
NMEA: The raw NMEA string from the GPS receiver
The circle on the right gives an overview of the satellites in view of the GPS receiver and which of them
are used from the receiver. The colour of the shown satellites indicates the signal strength of them.
From grey to dark green which is the strongest signal. Satellites shown in the centre of the circle are
directly above the GPS-aerial. Satellites shown at the border of the circle are near the horizon.
The field <PPS sync> and <Not fixed> change their colour from grey to green depending if the
appropriate feature is available at the moment (green means available).
