读取rinex文件的python代码

以下是一个简单的Python程序来读取RINEX文件：

import datetime

def read_rinex(file_path):
    with open(file_path, 'r') as f:
        obs_lines = []
        nav_lines = []
        header_lines = []
        for line in f:
            if line.startswith('OBS'):
                obs_lines.append(line)
            elif line.startswith('NAV'):
                nav_lines.append(line)
            else:
                header_lines.append(line)
    # 解析头部信息
    version = header_lines[0][5:20]
    sat_sys = header_lines[0][20:40]
    rec_type = header_lines[0][40:60]
    ant_type = header_lines[0][60:80]
    ...
    # 解析观测数据
    obs_data = []
    for line in obs_lines:
        s = line.split()
        prn = s[0]
        obs = [float(x) if x != '' else None for x in s[1:]]
        obs_data.append((prn, obs))
    # 解析导航数据
    nav_data = []
    for line in nav_lines:
        s = line.split()
        prn = s[0]
        t = datetime.datetime.strptime(s[1], '%y %m %d %H %M %S.%f')
        nav = [float(x) if x != '' else None for x in s[2:]]
        nav_data.append((prn, t, nav))
    return version, sat_sys, rec_type, ant_type, obs_data, nav_data

if __name__ == '__main__':
    file_path = 'example.16o'
    version, sat_sys, rec_type, ant_type, obs_data, nav_data = read_rinex(file_path)
    print(f'file version: {version}')
    print(f'satellite system: {sat_sys}')
    print(f'receiver type: {rec_type}')
    print(f'antenna type: {ant_type}')
    print(f'obs data: {obs_data}')
    print(f'nav data: {nav_data}')

在这个例子中，我们从一个RINEX文件中读取头部信息、观测数据和导航数据，并提供了一些简单的解析例子。这里只是一个简单的例子，你需要根据你实际的数据格式来进行调整。
