gnss

Global Navigation Satellite System

The gnss module contains classes to control the GNSS and acquire positioning information.

class gnss.GNSS

Get updated positioning information from Global Navigation Satellite System (GNSS)

Usage:

import gnss
import time

nav = gnss.GNSS([gnss.SatelliteSystem.GPS, gnss.SatelliteSystem.GLONASS])
last_print = time.monotonic()
while True:
    nav.update()
    current = time.monotonic()
    if current - last_print >= 1.0:
        last_print = current
        if nav.fix is gnss.PositionFix.INVALID:
            print("Waiting for fix...")
            continue
        print("Latitude: {0:.6f} degrees".format(nav.latitude))
        print("Longitude: {0:.6f} degrees".format(nav.longitude))
