A Multi-Site Quad-Band Radio Frequency Interference Monitoring Alerting and Reporting System

Abstract

This paper reviews the motivation behind and development of a deployable Radio Frequency Interference (RFI) detection, alerting and reporting system which simultaneously monitors all Global Navigation Satellite System (GNSS) L-band signal transmission for disruption, captures interference events, characterizes them, notifies stakeholders of event occurrence and lastly marshals the captured data to cloud storage. Results of a multi-site international deployment program are presented and discussed.
