Output number of satellite in view

[Buttosaii]

Hi, is there a command or function to output the number of satellite seen by the GNSS?

Hi @Buttosaii,

This is the sort of thing you could Google yourself (e.g. search on "NMEA number of satellites seen"), but in short the answer is yes, you can use the numSV (number of Space Vehicles i.e. satellites) attribute in NMEA messages like GGA, GNS or GSV, e.g.,

from serial import Serial
from pynmeagps import NMEAReader
stream = Serial('/dev/ttyACM0', 38400, timeout=3)
nmr = NMEAReader(stream)
(raw_data, parsed_data) = nmr.read()
if hasattr(parsed_data, "numSV"):
    print (f"Message type {parsed_data.identity}; Number of satellites tracked:  {parsed_data.numSV}")

Hope this helps.

FYI the u-blox support forum is also a useful resource for technical queries though, as I say, this sort of information is in the public domain.
