Here you can find data concerning global positioning satellite systems (either GPS-NAVSTAR or GLONASS), the status of the systems (number of working satellites and whether they are usable or not) and position data for all satellites. All data are based on the monitoring of both systems that we do here at the Czech Technical University in Prague.
Actual and archived almanacs for GPS and GLONASS published in YUMA format can be found at our FTP site.
Archived status, ionosphere and health records can be also found here:
Information about DGPS reference station you can find here.
