Finnish satellite sends world's first 75 GHz signals from space – a new high frequency range could ease clutter on the radio waves
The W-Cube nanosatellite sent a signal on the extremely high frequency range of 75 GHz on August 31st at 16:21 Finnish time. The signal was received successfully by the ground station in Graz, Austria. The satellite, ordered from Finland by the European Space Agency ESA is broadcasting the signal using a radio beacon system developed by VTT Technical Research Centre of Finland and Germany's Fraunhofer IAF. The satellite is now modelling, for the first time ever, how a 75 GHz signal can penetrate the earth's atmosphere. This opens possibilities for the utilisation of the high millimetre wave
