Ultra-wide spectrum electromagnetic pulse effect and experimental analysis of UAV GPS receiver

Based on the interference tolerance of UAV GPS receiver, this paper analyzes the mechanism of GPS ultra-wide spectrum strong electromagnetic pulse effect. It presents the effect test of high-repetition ultra-wide spectrum electromagnetic pulse jammer on typical micro-UAV and analyses high-repetition and ultra-wide spectrum electromagnetic pulse interference effects of UAV GPS receivers in different positions, different heights, different states, and different flight modes. The test results show that the high-frequency ultra-wide-spectrum electromagnetic pulse has different degrees of interference on the GPS, the image transmission system and the lower-view sensor of the UAV, and the interference can be within a certain range by interfering with the GPS receiver of the UAV. The interference can cause drone's failure to take off normally, even make the UAV out of control during the flight process. It is verified that the high-repetition ultra-wide spectrum electromagnetic pulse will cause interference to the GPS receiver, making the GPS unable to work.
