Dear All,
the S5Lab research team of the University "La Sapienza", Rome, Italy, the Italian Space Agency and AMSAT Italia are happy to inform the ham radio community that the GreenCube satellite will be switched in digipeater mode between 29-Oct-2022 00:01 UTC and 30-Oct-2022 23:59 UTC. Information on the setup required to access the satellite can be found on the team's web site https://www.s5lab.space/index.php/digipeater/.

The S5lab team of Sapienza provides the software needed to communicate with the satellite along with a technical guide of the setup and the GUI features. The  archive contains:

    • The user manual
      • The Graphical User Interface (GUI)
      • The Terminal Node Controller (TNC) software
        • The GNURadio script to receive and transmit

        The software kit can be downloaded from the same web page. The satellite digipeater implements a store-and-forward message service and works at 435.310 Mhz (U/L and D/L).

        The 3U cubesat was launched on the Vega-C maiden flight on 13-Jul-2022 in a MEO orbit. The GreenCube project is being carried out through a collaboration agreement between the Italian Space Agency and Sapienza University of Rome, with the participation of ENEA and University Federico II of Naples. As for the radio frequency communications, a strong and effective cooperation with AMSAT Italia has been established, whereby AMSAT Italia endorsed the frequency coordination request.

        The team can be reached via their website at the URL https://www.s5lab.space/index.php/contact-us/.
