如何使用python读取nmea文件

def read_nmea_file(file_path):
    with open(file_path, 'r') as file:
        for line in file:
            if line.startswith('$GPGGA'):  # 以$GPGGA开头的行包含位置信息
                data = line.split(',')
                latitude = data[2]
                longitude = data[4]
                print(f"Latitude: {latitude}, Longitude: {longitude}")

# 调用函数并传入NMEA文件路径
read_nmea_file('path/to/nmea_file.txt')

pip install pynmea2

import pynmea2

def read_nmea_file(file_path):
    with open(file_path, 'r') as file:
        for line in file:
            try:
                msg = pynmea2.parse(line)
                if isinstance(msg, pynmea2.GGA):  # 只处理GGA消息
                    latitude = msg.latitude
                    longitude = msg.longitude
                    print(f"Latitude: {latitude}, Longitude: {longitude}")
            except pynmea2.ParseError:
                continue

# 调用函数并传入NMEA文件路径
read_nmea_file('path/to/nmea_file.txt')
