Brief description

GPS daily files in RINEX v2 format with International GNSS Service format log files in a single tar file. Files are compressed using gzip after 'Hatanaka' compression.

Compression information: Yuki Hatanaka (hatagsi.go.jp) (GSI) wrote and maintains rnx2crx and crx2rnx, which allows the user to compress/decompress, respectively, a RINEX observation file into a smaller ASCII format. The Hatanaka-compressed ASCII format version of a RINEX observation file is frequently used in conjunction with the UNIX compress, zip, gzip or other generalized compression utilities to create a very small file for Internet transfer.

Compression information: open utlities rnx2crx and crx2rnx allow the user to compress/decompress, respectively, a RINEX observation file into a smaller ASCII format. The Hatanaka-compressed ASCII format version of a RINEX observation file is compressed here with gzip.

RINEX files are stored in the following structure within the tar file.
./YYYY/DDD/YYt/mmmmDDD#.YYt.gz

YYYY=4-digit year
DDD=3-digit day of year
mmmm=4-char site name
#='0'
YY=2-digit year
t='o'

IGS log files are in
./logs


Approximate site locations are given below in units of decimal degrees (WGS84) as (latitude longitude) pairs:

BHIL -66.251024752 100.599006649 Bunger Hills site, originally established by Geoscience Australia

Data spans December 2015 to Jan 2019 but exact durations depend on the site.
