Two ground stations are being used to support SwissCube for redundancy:one at EPFL, and one at HE-Fribourg. The HE-Fribourg ground station has already received digital data transmitted by a radio amateur satellite. The uplink has 11.4 dBi of antenna-gain (one crossed 9-element yagi). The downlink has 14.5 dBi of antenna gain (one crossed 17-element yagi). The second ground station is located at EPFL in Lausanne. The performances of the EPFL ground station are slightly higher than the performances of the Fribourg ground station as there are 4 70-cm yagi antennas in reception (20.4 dBi gain) and 2 2-m yagi antennas in emission (13 dBi gain).
