The Satellite Applications Catapult's GNSS Performance Quantification System will use a network of remotely deployed interference sensors to collect GNSS data and to measure interference at a wide selection of sites in a region of the United Kingdom. Ionospheric characteristics including scintillation and other parameters will be separately collected, and a Signal Monitor System will collect GNSS satellite transmissions. This data will be combined with other relevant information addressing a selection of Global Navigation Satellite Systems including the US GPS System and the European Galileo System. Other GNSSs may be subsequently included. This System will be used to assess a wide variety of performance metrics including constellation health, satellite performance, ionospheric characteristics, and interference characteristics. Where appropriate, the regional distribution of ionospheric and interference characteristics will be parameterized. This paper presents an overview of this nascent System of Systems, and explains in detail the Interference Characterization System. The implementation and initial measurement campaign has recently started, and is planned to extend for two years. Results will be available early after deployment, but long-term characterization is desired, firstly for scientific rigour, and secondly to monitor whether threats change with time.
