This thesis investigates the usage of automatic direction finding in the Asian Hornet tracking field. A lightweight and portable design with a precision of 0.5 degrees is discussed and implemented. The goal of this localization system is to track the transmitter that is attached to the Asian Hornet. The system utilizes two Software Defined Radio (SDR) dongles from the brand RTL that receive the transmitted signal from the transmitter and send it to the computer. The Angle Of Arrival of the signal is calculated using phase interferometry. The results show that the Python program, the algorithm implementation in combination with the used hardware, used to calculate the phase difference is not fast enough to process the received signal in real time. Furthermore, the chosen RTL SDR dongles cannot be synchronized easily which leads to unknown and varying phase differences when receiving the signals.
