In August 2006, a calibration base for testing the antennas was put into operation on the roof of the IRSM building in Prague (PRAH).
After storage on the PC's internal hard disk, the data are automatically transferred to the IRS operational centre in the IRSM, using an Internet connection.
2005a, Transmission of continuously recorded data from remote GPS permanent stations to IRSM control unit.
2004a, Permanent GPS observatories operated by the IRSM Acad.
In the frame of the collaboration of the IRSM with Agriculture University of Wroclaw, Department of Geodesy and Photogrammetry, GPS measurements in the Czech side were completed by GPS registration on the Polish point on the Snezka Mt.
Observatory POST, the last IRSM observatory is situated on the highest floor of a prefabricated house in Poustka, which is a part of Frantiskovy Lazne town.
In view of higher transfer speed and the payment according to the amount of transmitted data and not according to their transfer time the GPRS technology i s highly suitable for the data transfer from observatories to the server of an institution carrying on their operation, in our case from the observatories BISK, MARI, POST and SNEC to the IRSM server.
Data transfers between the PC and the IRSM server were tested for several months.
In the present period entire RINEX data file stored during 24 hours on observatory PC is transferred to the IRSM server about 40 minutes.
