d GLONASS data type?
The RINEX observation data have been “compacted” using software developed by Yuki Hatanaka/GSI and then compressed using standard UNIX compression. By using the Hatanka software with standard UNIX compression, the RINEX observation files have been reduced in size by a factor of 2.5. Users must first use the UNIX uncompress command (or equivalent software), then run the cmp2rnx software to un-compact the uncompressed file; the resulting file is a GLONASS observation file in RINEX format.
