Monitoring surface elevation change and ice sheet movement in Antarctica using high-precision GPS techniques

The data sets consist of static and kinematic GPS data collected on the Amery Ice Shelf using Leica 299 receivers. Additional GPS data were collected at Beaver Lake. All data are provided in UNIX Z compressed RINEX (Receiver INdependent EXchange) format, as described in the IGS standards - see igs.org/products The standard RINEX file naming convention is used, i.e., an eight digit file name as bbbbddds.yyt, where bbbb refers to a four digit station name, ddd refers to the day number of the year, s refers to a session number and yyt is the file extension number where yy refers to the year and t defines the file type (o for observation file and n for navigation file).

All files are compressed using the UNIX Z compression scheme, as shown by the extension .Z. For example, base0010.95o.Z and base0010.95n.Z. The files are set out in the following directories on the ftp site: season1995_1996 \beaver \camp GPS data collected at the permanent stations at Casey, Davis and Mawson are available from Geoscience Australia - see ga.gov.au/scientific-topics/positioning-navigation/geodesy The fields in this dataset are: GPS marker number marker name observer/agency approximate position antenna wavelength interval
