GEPOS: Geophysical laboratory and observatory infrastructure of FIN-EPOS

2015–2018          A fibre link to transfer coordinate universal time Metsähovi observatory

The main objective for VTT is, in collaboration with the Finnish Geospatial Research institute of the National Land Survey of Finland, to construct a fibre-optic frequency and time transfer link between VTT MIKES Metrology and Metsähovi Radio Observatory. This will enable the linking of the atomic clocks, the satellite laser ranging telescope and other equipment at Metsähovi with the Finnish realization of coordinate universal time generated at MIKES Metrology.
