Dear colleagues,

I would announce a release of an updated version (4.1.0) of the RINEX compression software RNXCMP.

The updated software packages are available from GSI's server:
https://terras.gsi.go.jp/ja/crx2rnx.html

The followings are changes from version 4.0.8 to 4.1.0.
   - RINEX ver.4.xx files are accepted as inputs. The correspondence between versions of RINEX format and those of Compact RINEX format is as follows:
            RINEX          Compact RINEX
          ver. 2.xx  <--->    ver. 1.0
          ver. 3.xx  <--->    ver. 3.0
          ver. 4.xx  <--->    ver. 3.0

   - The front-end tools RNX2CRZ.bat and CRZ2RNX.bat for Windows are replaced with completely new ones. Long filenames or old short filenames of RINEX conventions are assumed for input RINEX and Compact RINEX files and output RINEX files, accordingly. For old short file names of compressed files, NOT VMS/DOS types, but only UNIX types can be handled. The old DOS tools, that can handle short file names of compressed files of VMS/DOS types, are obsolete and not provided any more.

   - The default command is now "gzip" instead of "compress" for the text compression in the front-end tools.

   - Following bugs of RNX2CRX are corrected:
       + Error in case the number of special records exceeds 99 in RINEX ver.2 files.
       + Error in case clock offset is padded with spaces in RINEX ver. 3 or 4 files. 
       + Error in case a bad GNSS type is detected even if option -s is specified with RNX2CRX.

If you have any questions or feedback, contact me or Dr. Satoshi Kawamoto (kawamoto-s96tf @ mlit.go.jp) of GSI. 


Sincerely,

Yuki Hatanaka
