GNSS Interference Monitoring from LEO

Register for the Final Presentation of the NAVISP EL2 -117 Project “GNSS Interference Monitoring from LEO.

The increasing societal reliance on GNSS and complementary RF-based PNT systems has motivated the development of solutions to address the threat of RF interference to these systems.

Nowadays, malicious sources of RF interference are widely used both by civil and military entities, because of the proliferation of inexpensive software-defined transmitters and the evolution of electronic warfare.

This situation motivates technology providers to deliver situational awareness for users of GNSS and alternative PNT systems in a timely manner and at a global scale.

In this context, Spire has prototyped a service for RF interference monitoring in L-band that leverages Spire's constellation of GNSS Reflectometry and Radio Occultation nanosatellites. The goal is to detect interference against GNSS receivers, both in the form of jamming and spoofing, and to geolocate the sources on ground using one or multiple satellites in LEO.

As part of NAVISP EL2-117 project, Spire has demonstrated the capabilities of the prototype service mainly in two experiments: during a public GNSS interference exercise in the Nevada Test and Training Range, United States, and over Syria, where interference events have already been investigated in the scientific literature.

The project was carried out in the frame of NAVISP Element 2, which is devoted to supporting competitiveness of European industries.
