A new satilite supporting APRS will be orbiting the earth soon. The QIKCOM-1 module containing an APRS transponder and Terrestrial Alert beacon will be deployed from the ISS on 21 Aug 2017.
Built as a student project Amateur Satellite module at the Naval Academy, and attached to the NovaWurks SIMPL spacecraft, it will function identically to the ISS transponder on 145.825 MHz with the same ARISS alias and once they widely separate, will permit possible dual-hop experiments between it and the ISS APRS digipeater.
