Research on optimum scheme of GPS receiving sensitivity with holographic interference

This paper is mainly aimed at the vehicle GPS system being interfered after the vehicle is powered on, and the signal strength does not meet the design requirements. According to the scientific elimination method, we find that the holographic indication equipment containing the DDR unit is the main source of electromagnetic disturbance, and the mechanism of disturbance is analyzed and studied. Finally, considering the key elements of the vehicle, an engineering optimization scheme is introduced to make the GPS receiver meet the design requirements.
