Continuous Localization-Assisted Collaborative RFI Detection Using the COTS GNSS Receivers †

Abstract

Radiofrequency Interference (RFI) is a growing concern for many navigation-reliant applications. The dual benefits of RFI localization are considered: first, it can help with situational awareness by estimating the location of the interference source, and secondly, the results can be used to verify the detection of significant interference. The paper exploits the latter by proposing detection techniques making use of the localization results. The performance of the algorithms is evaluated using an experiment in a controlled lab environment where a wideband interference source is emulated in a UAV-based scenario. The detection results are validated using a reference detector operating in a non-position domain.
