in GPGSA frames
Elevation The elevation (up-down angle between the dish pointing direction) in
degrees as stated in GPGSV frames
Azimuth The azimuth (rotation around the vertical axis) in degrees as stated in
GPGSV frames
SNR The SNR (Signal to Noise Ratio), often referred as signal strength
Please note that the values are shown as calculated by the daemon, their accuracy might be sugges-
tive.
Supervision
Parameter GNSS Supervision
Administrative status Enable or disable GNSS supervision
Mode Specifies whether to monitor the NMEA stream or GPS fixes
