Hanataka-compressed RINEX Format

The RINEX files stored in SatRef server are compressed by RNXCMP software. RNXCMP is the software for compression/restoration of RINEX observation files developed by Yuki Hatanaka of Geospatial Information Authority of Japan (GSI). It converts the format of GNSS observation files from the RINEX format (version 2.xx or 3.xx) to a compressed format (the CompactRINEX format, or often called the Hatanaka-compressed format) and vice versa. Please visit GSI website for details.

A simple VBScript program Extract.vbs is developed by Lands Department to restore SatRef's Hatanaka-compressed RINEX files. Click here to open 'Extract.txt' for details.
