无人机载干扰设备及导航GPS的电磁兼容性探究

Electromagnetic Compatibility of UAV Jamming Equipment and Navigation GPS

本文通过研究无人机机载干扰信号发射源对机载导航GPS模块的影响,试图提升机载导航GPS模块的抗干扰能力,以提升机载导航GPS模块的电磁兼容性。通过对GPS模块的干扰原理进行分析,找到在硬件上提升机载GPS模块抗干扰能力的解决方案,进而再通过软件算法对其抗干扰能力进行提升。该算法借鉴了俄罗斯联盟号飞船等航天技术的抗干扰设置方式,将民用无人机的电磁管理给与提升。本文认为,该系统虽然仅考察了GPS模块的抗干扰能力,并没有对其平差、伪距等计算进行深化分析,但提升了系统抗干扰能力,可以有效提升人机机载GPS模块的测量精度,使其发挥最大效用。

This paper studies the influence of UAV airborne interference signal source on the airborne navigation GPS module,and tries to improve the anti-interference ability of the airborne navigation GPS module,so as to improve the electromagnetic compatibility of the airborne navigation GPS module.Through the analysis of the interference principle of GPS module,the solution to improve the anti-interference ability of Airborne GPS module in hardware is found,and then the anti-interference ability is improved by software algorithm.This algorithm improves the electromagnetic management of civil UAV by referring to the anti-interference setting mode of space technology such as Russian Soyuz spacecraft.This paper considers that although the system only studies the anti-interference ability of GPS module,and does not make a deep analysis of its adjustment and pseudo range calculation,it improves the anti-interference ability of the system,which can effectively promote the measurement accuracy of the UAV Airborne GPS module and make it play the maximum role.
