In case of UAVs (Unmanned Aerial Vehicles, commonly known as a drone), reliable communication is very important factor between the ground control station and them.

Ardupilot -which is an open source autopilot system- usually uses 430Mhz ISM radio for this purpose.

This thesis examines how cellular networks (as LoRa and LTE) can be an alternative to this radio.

First it is important to know how LoRa and Ardupilot works, for this purpose the first and second chapter gives an overall. After that, I had to develop the system, which enables the communication between the drone and the ground control station through LTE and LoRa network. As a result, we get a redundant radio system, which has an infinite range between the drone and the ground control station, when it flies within a network covered area.

At the end of the thesis a flight is presented driven with the developed system, and also an evaluation of the collected radio parameters, and the examination of these communication technologies' usability for UAV systems.
