Metadata details

AAS_4318_GNSS_bedrock_raw_data

All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    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.
