Radiolabs has attended the ION’s International Technical Meeting (ITM) held January 21-24, 2020 in San Diego, California presenting the paper GNSS Anti-jam RF-to-RF On Board Unit for ERTMS Train Control in the GNSS and Security Session on Jamming and Spoofing. Pietro Salvatori of Radiolabs underlined in his presentation the possible GNSS interference scenarios to be analyzed and mitigated to ensure the ERTMS – European Railway Traffic Management System can operate with GNSS positioning without degradations. The solution developed by Radiolabs in the frame of the ESA DB4Rail project and consisting of a 4-element active antenna with a processing chain to detect and mitigate the interfering signals can now be integrated into the GNSS Automated Virtualized Test Environment for Rail (GATE4Rail) under development to create a unified test bed architecture. Combining the Anti-Jam solution with the GATE4Rail platform, the GNSS positioning resilience to RF interference and jamming can be evaluated in a controlled environment that otherwise would require severe constraints and high costs.
