Abstract

Global Navigation Satellite Systems (GNSS) are vulnerable to Radio Frequency Interference (RFI). Prior work proposed the use of an Extrapolated Single Propagation Particle Filter (ESP-PF) to geo-locate RFI sources. This work describes a hardware implementation of the ESP-PF on a Xilinx Field Programmable Gate Array (FPGA). It provides a detailed analysis of fixed-point ESP-PF modelling and discusses ways to minimise its impact. Performance analysis shows that the hardware implementation produces position estimates that are comparable to and sometimes exceed that of the floating-point implementation. The hardware implementation enables ESP-PF to be used in real-world applications to geo-locate multiple RFI sources via time-multiplexing.
