get_bits(self)

source code 

Child classes must implement this. Return a BitVector representation. Child classes do NOT include the Message ID, repeat indicator, or source mmsi

get_aivdm(self, sequence_num=None, channel='A', normal_form=False, source_mmsi=None, repeat_indicator=None)

source code 

return the nmea string as if it had been received. Assumes that payload_bits has already been set

Parameters:
  • sequence_num - Which channel of AIVDM on the local serial line (in 0..9)
  • channel - VHF radio channel ("A" or "B")
  • normal_form - Set to true to always return aone line NMEA message. False allows multi-sentence messages
Returns: list (even for normal_form for consistency)
AIVDM sentences

kml(self, with_style=False, full=False, with_time=False)

source code 

return kml str for google earth

Parameters:
  • with_style - if style is True, it will use the standard style. Set to a name for a custom style
  • with_time - enable timestamps in Google Earth
