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.

The file naming follows the convention "NNNNddds.yy" where:

"NNNN"
is the site name; AAUC for this one
"ddd"
refers to the day of the year,
eg. 056 corresponds to Feb 25th
"s"
is the session number, eg. 0
"yy"
is the two last digits of the year
