Usage: #{__FILE__} GPS_file1 GPS_file2 ...
As GPS_file, rinex_nav(*.YYn, *.YYh, *.YYq), rinex_obs(*.YYo), and ubx(*.ubx) format are currently supported.
File format is automatically determined based on its extention described in above parentheses.
If you want to specify its format manually, --rinex_(nav|obs)=file_name or --ubx=file_name are available.
Supported RINEX versions are 2 and 3.
Note: YY = last two digit of year.
