Our fixed wing UAV, designed by GMG (Geohazard Monitoring Group –  http://gmg.irpi.cnr.it) of CNR IRPI was recently equipped with HD CAM live streaming through TCP/IP protocol.
Due to long distances covered by the aircraft, main target is to transmit at long distances (several kilometers) FPV video streaming with HUD telemetry, using a low cost smart device with a LTE SIM data connection.To do this, a completely free and open source hardware configuration was choosen.
Main hardware is composed by a Raspberry Pi who send data to one or more endpoint that can be reached by a Ground Control Station connected to internet.
The flight can so be followed and managed by a Ground Control Station and/or by video streaming (telemetry is HUD aviation compiliant) trough a  Raspberry SSH tunneling  for aerial navigation and settings modification.
In addition, video streaming is reachable from any location equipped with an internet conection (tablet and/or laptop).
