The European Space Agency (ESA) has signed a contract with Norwegian company Testnor for the development of a library of GNSS interference recordings and radiofrequency (RF) playbacks for industry use. The project follows a call for projects by the Norwegian Space Agency to support the development of resilient positioning, navigation and timing (PNT) solutions.

Funded through ESA’s Navigation Innovation and Support Programme (NAVISP), the service will be built on GNSS interference recordings, starting with data collected at Jammertest, the Norwegian government’s annual open-air GNSS interference exercise coordinated by Testnor and recognised as the world’s largest event of its kind.
As demand grows for resilient PNT technologies, access to authentic interference data is becoming increasingly important for companies developing GNSS receivers, chipsets, anti-jam and anti-spoofing antennas, as well as critical infrastructure operators and system integrators.
Yet access to real-world interference environments remains tightly regulated, limiting opportunities for testing under representative conditions.
To address this gap, Testnor will create a curated online Signal Data Library. Customers worldwide will be able to license authentic multi-constellation GNSS interference recordings and access a laboratory RF replay service. This will allow them to perform realistic tests to assess the vulnerabilities of their technologies, validate performance and strengthen overall resilience.
Over the next two years, the Tromsø-based company will mature the service to Technology Readiness Level 9 (TRL 9) with the aim of delivering a fully operational commercial offering for the global Positioning, Navigation and Timing (PNT) market.
“Testnor has already proven its value by contributing to the development of Jammertest, one of Norway’s most important contributions to GNSS resilience. Through NAVISP, we are helping Testnor transform that experience into a market-ready service that will make authentic interference data accessible to industry,” says Rafael Lucas Rodriguez, Head of NAVISP at ESA.
“We are scaling our services and building the capacity Europe needs, with the support of the European Space Agency’s NAVISP programme. This makes realistic testing available to the entire GNSS industry, so they can build and validate resilient products,” says Ingrid Dahl Skarstein, Chief Operating Officer and co-founder of Testnor.
