MarconISSta experiment identified ON4ISS signals

The project leader and initiator of MarconISSta, Martin Buscher DJ1MBB, has requested some support to help categorise the antennas on the ISS.  The ARISS telebridge groundstation ON4ISS reacted immediately and transmitted at different ISS passes the desired signal to the ISS.

This experiment ended Feb 7th 2019 at midnight (UTC) and only receive signal strength value for 435-438 MHz without decoding data. MarconISSta was deinstalled on Saturday, February 9th 2019, by NASA astronaut Anne McClain.

The project is conducted by a team of researchers and students from Technische Universität Berlin with support of DLR, ESA, ARISS and other partners.
