System for detecting GNSS signal jammers, which is intended to be positioned on a roadside, the system comprises a first device (MSG) for receiving a GNSS signal; a second device (DBR) that is configured to measure at least one characteristic of a received GNSS signal and to detect, on the basis of said at least one characteristic, interference in said GNSS signal caused by a jamming signal; a third device (FLASH) for triggering the capture of an image of the road if said GNSS signal is subject to interference caused by a jamming signal, the first device (MSG) being configured to receive, viaa radio link, a sequence of a satellite radio navigation signal received by a vehicle (VEH) and retransmitted by said vehicle (VEH) to the system (SBDR) via the radio link. 本申请涉及用于检测个人GNSS干扰机的系统，所述系统旨在置于路边，所述系统包括：-第装置(MSG)，其用于接收GNSS信号；-第二装置(DBR)，其配置为测量接收到的GNSS信号的至少个特性，并且基于所述至少个特性来检测由干扰信号引起的所述GNSS信号中的干扰；-第三装置(FLASH)，其用于如果所述GNSS信号受到由干扰信号引起的干扰，则触发对道路的图像捕捉，所述第装置(MSG)配置为经由无线电链路接收由车辆(VEH)接收并且由所述车辆(VEH)经由无线电链路转发至系统(SBDR)的卫星无线电导航
