This SINEX was gzipped and then split into 1GB chunks to alleviate the download process. To restore the original file, one can simply use the commands cat GOCO06s_normalEquation.snx.gz.part* > GOCO06s_normalEquation.snx.gz on Linux/Unix or type GOCO06s_normalEquation.snx.gz.part* > GOCO06s_normalEquation.snx.gz on Windows. The resulting file can then be gunzipped (Warning: the resulting ASCII file will become quite large).
