Final Presentation of NAVISP Project EL3-015 now available:
On Monday, November 21, 2022, SINTEFF, together with the University of Helsinki, presented the results of the NAVISP project “Advanced Radio Frequency Interference Detection, Alerting and Analysis System (ARFIDAAS) II.” Over 50 people from industry and research followed the interesting presentation and the subsequent interactive Q&A session.
Radio frequency interference (RFI) from personal private devices is known to occur on the world's roadways, and the frequency of occurrence is increasing. Measurement campaigns have shown that sites adjacent to busy roads can expect to be exposed to RFI, with collected sites having a higher probability of jamming activities.
Existing solutions offered so far very limited spectral coverage, which the ARFIDAAS (Advanced Radio Frequency Interference Analysis and Alerting System) project addressed by simultaneously covering all current Galileo, GPS and GLONASS signals and providing threat assessment mechanisms to improve both, detection and alerting, while also building a database of known threats.
In a first ARFIDAAS project a combined hardware and software system was developed which was capable of detecting the presence of RFI, capturing it, notifying interested parties with a preliminary analysis, and capturing the raw and processed data for subsequent use in centralized cloud storage.
Building on this, the ARFIDAAS II system hardware and firmware were upgraded and modified. In addition, the COTS computer system software was updated to add additional reporting capabilities and optimized to reduce message latency at the same time. Finally, the all-new cloud-based portions of the system architecture were added.
Consequently, the ARFIDAAS2 project improved the system's suitability for enforcement, reduced detection latency, increased the detail of reports and sought to enable identification of individual jammers over time and location. In addition, the project addressed the specific challenges of using GNSS signals in Finland, while building a wider network of multi-band monitoring stations that provide more information with lower latency to stakeholders in the field.
ARFIDAAS II was also applied in the scope of the Jammertest 2022, which was an event organized by the Norwegian Communications Authority together with the Norwegian Public Roads Administration, and the Norwegian Defense Research Institute in northern Norway in September 2022. The event aimed to provide a unique opportunity for participants to test GNSS jamming and spoofing of equipment in controlled conditions. During the project, a large database was created with over 13 000 events monitored, including numerous spoofing tests from Jammertest, as well as thousands of examples of various types of Personal Privacy Devices (PPDs), unintentional jamming, and unknown sources. If you are interested in using this data, please do not hesitate to contact us (navisp@esa.int) or SINTEF directly.
The project was part of NAVISP Element 3, aiming to support national PNT strategies by providing support per country and possibly per domain for the development and promotion of products, applications and services based on PNT systems to foster national and international cooperation.
