Estimation of the Effect of Single Source of RF Interference on an Airborne GNSS Receiver, A Theoretical Study and Parametric Simulation

This paper addresses the critical issue of unwanted interference in airborne GNSS receivers, crucial for navigational safety. Previous studies often simplified the problem, but this work offers a comprehensive approach, considering factors like Earth's reflective properties, 3D calculations, and distinct radiation patterns. It introduces SPIDEH and OEP graphs to visualize interference distribution along flight paths. Results highlight the significance of physical configuration and distance from interference sources on receiver performance. The algorithm developed can assess interference effects on GNSS receivers and aid in selecting optimal flight paths for minimal interference. This research enhances understanding and management of unintentional interference in airborne navigation systems.
