The GPS reference receiver at Aalborg University
DGC continuously operates a reference station at Aalborg University. This station provides Global Positioning System (GPS) carrier phase and code range measurements. Surveyors, engineers, scientists, and students can apply these data to position points at which user data have been collected.
The tracking data is provided as Zip compressed RINEX files, and the daily compressed RINEX file contains an observation file and a navigation message file. Data rate is 30 seconds, and all files contain observations for a 24 hour period, from 00:00:00 till 23:59:30 GPS time. The navigation message files contain the broadcast messages collected by the tracking station between 00:00 and 23:59 GPS time.
Observation files can be downloaded here:
The file naming follows the convention "NNNNddds.yy" where:
is the site name; AAUC for this one
refers to the day of the year,
is the session number, eg. 0
is the two last digits of the year
The Aalborg University reference station site coordinates are:
The cartesian coordinates are referenced with respect to the International Terrestrial Reference Frame 1996 (ITRF96), and the geodetic coordinates are referenced with respect to the World Geodetic System 1984 (WGS84).
