TY - JOUR AU - Cao, Zhuojian AU - Liu, Jiang AU - Jiang, Wei AU - Cai, Baigen PY - 2025 TI - INS-aided GNSS jamming protection in support of resilient train positioning JO - High-speed Railway SN - 2097-3446 SP - 185 EP - 193 VL - 3 IS - 3 AB - Railway safety and efficiency increasingly rely on precise train positioning. The integration of the Global Navigation Satellite System (GNSS) into railway control systems aims to reduce dependence on track-side infrastructure. While GNSS has significantly improved train localization, challenges such as the susceptibility to jamming remain. To address this, this paper introduces an Inertial Navigation System (INS)-aided train positioning system based on deep integration, exploring its performance through semi-physical experiments and simulations. Experimental results demonstrate that the proposed solution is able to reduce the positioning error by 63.47 %, and the velocity error by 58.47 % under jamming conditions. The study highlights the potential of deep integration for improving the resilience of GNSS-based train control systems, especially in the face of Radio Frequency (RF) jamming threats.
