Dear colleagues,

the most recent comparison between various RINEX converters (generation of
GLONASS navigation message files) revealed some minor problems. May I ask you
to look into it if it concerns your converter.

The format description can be found on

   Internet:   ubeclu.unibe.ch
   User:       anonymous
   Directory:  aiub$ftp/rinex
   File:       rinex2.txt, see also gln_clock.txt

Thank you very much for your cooperation.

Best regards,

Werner Gurtner
