gnssrefl.nyquist_cl.main()
gnssrefl.nyquist_cl.nyquist(station: str, lat: float = None, lon: float = None, el_height: float = None, e1: float = 5, e2: float = 25, samplerate: float = 30, system: str = 'gps')

Creates nyquist plot

Examples

nyquist sc02 -e1 5 -e2 15

typical case for most geodetic sites, 30 seconds, elevation angles 5-15 degrees

nyquist sc02 -samplerate 15 -system galileo

receiver sampling rate of 15 seconds and galileo

Parameters:

  • station (str) – 4 ch station name

  • lat (float, optional) – latitude in deg

  • lon (float, optional) – longitude in deg

  • el_height (float, optional) – ellipsoidal height in m

  • e1 (float) – min elevation angles (deg)

  • e2 (float) – max elevation angles (deg)

  • samplerate (float) – receiver sampling rate

  • system (str, optional) – name of constellation (gps,glonass,galileo, beidou allowed) default is gps

Return type:

Creates a png file, stores in $REFL_CODE/Files/station
