Working with the program

[1030ahmad1030]

Can you elaborate further on how to work with this your program? I have been struggling with it and it's yet to work for me.
I wrote the following:
from gnss_tec import rnx
from gnss_tec.glo import collect_freq_nums

glo_freq_nums = collect_freq_nums('C:/Users/ahmad/Desktop/hocam data2.20I')

with open('site0390.17o') as obs_file:
reader = rnx(obs_file, glo_freq_nums=glo_freq_nums)
for tec in reader:
print(
'{} {}: {} {}'.format(
tec.timestamp,
tec.satellite,
tec.phase_tec,
tec.p_range_tec,
)
)
and I had the following error:-
NavMessageFileError Traceback (most recent call last)
in
2 from gnss_tec.glo import collect_freq_nums
3
----> 4 glo_freq_nums = collect_freq_nums('C:/Users/ahmad/Desktop/hocam data2.20I')
5
6 with open('site0390.17o') as obs_file:

~\Anaconda3\lib\site-packages\gnss_tec\glo.py in collect_freq_nums(file)
57 file_handler = file
58
---> 59 for slot, epoch, f_num in nav(file_handler):
60 if f_num in freq_num_timestamps[slot]:
61 continue

~\Anaconda3\lib\site-packages\gnss_tec\nav.py in nav(file)
152 else:
153 raise NavMessageFileError(
--> 154 'Unsupported version: {}.'.format(rnx_version)
155 )

NavMessageFileError: Unsupported version: 1.0.
