A Laboratory Testbed for GNSS Interference Impact Assessment
Radio frequency interference (RFI) is of high interest
due to the increasing number of wireless applications and
the corresponding high occupancy of the spectrum. Global
navigation satellite systems (GNSS) are in particular vulnerable
for interference, since the received signal power
levels are very low. In this paper, we present a laboratory
testbed for the evaluation of the impact of RFI on GNSS
signals. The error vector magnitude (EVM) is proposed as
a metric to quantify the performance reduction in the presence
of interfering signals. The signal quality is analysed in
different interference scenarios. The measurement results
show that the EVM is a valuable metric for signal quality
and receiver performance estimation.
