The Advanced RFI Detection, Analysis, and Alerting System (ARFIDAAS) is a European space agency navigation, innovation, and support program (NAVISP) Element 3 initiative started in 2018, focusing on the capture and collection of radio-frequency interference (RFI) events impacting GNSS L-band signals. One of the key features of the ARFIDAAS project is that it utilizes custom monitoring hardware front-ends to simultaneously observe at least 240 MHz of aggregate spectrum divided into four tunable sub-bands. The typical configuration is of one covering the L1 band including BeiDou B1 through GLONASS G1 signals, and the other three partially overlapping bands spread between the Galileo E5a+E5b, GPS L2, and Galileo E6 signals.The primary motivation for developing ARFIDAAS was that the state of the art of previous GNSS RFI monitoring campaigns had limitations in the context 1 SINTEF AS

BiographyAiden Morrison received his PhD degree in 2010 from the University of Calgary, where he worked on ionospheric phase scintillation characterization using multi frequency civil GNSS signals. Currently, he works as a senior research scientist at SINTEF. His main research interests are in the areas of GNSS and multi-user collaborative navigation systems and GNSS RFI monitoring and analysis.Nadezda Sokolova received her PhD degree in 2011 from Norwegian University of Science and Technology (NTNU), where she worked on weak GNSS signal tracking and use of GNSS for precise velocity and acceleration determination. She is now working as a senior research scientist at SINTEF, and adjunct associate professor at the Engineering Cybernetics Department, NTNU, focusing on GNSS integrity and multi-sensor navigation for autonomous system operations.
