|Abstract:||This paper discusses interference issues in Unmanned Aerial Systems (UAS) and addresses the benefit of advanced monitoring and mitigation capabilities built into the GNSS receiver module. First the paper discusses experimental results of interference of UAV electronics into the GNSS sensor. The analysis is based on a specific RF signal monitoring technique built into the receiver module. Several ways to mitigate this self-interference are discussed. Furthermore the impact of various types of jammers on GNSS reception is experimentally analyzed. A recorded UAV flight is recreated with an RF constellation simulator, adding interference from various jammer types. The interference level is controlled according to electromagnetic propagation laws, taking into account the attitude of the UAV and its antenna radiation pattern. In this way we evaluated the performance of several receivers under jamming exposure, proving effectiveness of advanced interference mitigation.|
