This paper documents the current status of the Fundamental Station Wettzell. The objectives were pointed out and the changes from the satellite observation station to a geodetic observatory, to the Fundamental Station (FS-) Wettzell, with its space techniques such as SLR/LLR, VLBI, GPS, GLONASS and PRARE and with its facilities for local measurements such as a gravitymeter, seismometer, watervapour radiometer and its time and frequency system will be described. The local geodetic networks and methods for the footprint monitoring and for obtaining the local ties between the reference points of the system will be presented. The contribution of the FS-Wettzell within the international activities will be summarized. The development of the Transportable Integrated Geodetic Observatory TIGO is strongly correlated with the experiences gained from the work at Wettzell. The development of TIGO enbeded in the work of Wettzell will be shown to round up the current status. Information will be given on the developments of the lasergyroscopes "CII" and "G", which will result in real time monitoring of the variations of the Earth ratation parameter DUT1.
