RINEX Hatanaka Compressed Files

Hatanaka RINEX compressed files are not directly supported, but the Hatanaka RINEX compression or decompression can be combined with gfzrnx using the standard in/output (via pipes).

The Hatanaka RINEX compression/decompression utilities RNXCMP are free software and can be downloaded from http://terras.gsi.go.jp/ja/crx2rnx.html.

On the following page, you can find some examples of the RNXCMP decompression/compression in combination with gfzrnx and gzip compression. 

Decompression:
--------------
