基于软件无线电的GNSS欺骗方法及系统设计
Design of GNSS Spoofing Method and System Based on Software Defined Radio
摘要
Abstract
In order to solve the problems of existing spoofing methods,such as high jamming power,easy to cause secondary injury,this paper proposes a global navigation satellite system(GNSS)deception method based on software-defined radio.The method reconstructs the baseband signals of the deception signals through the transmission time,Doppler frequency,navigation messages and other information of the real signals,and converts the digital baseband signals into radio frequency signals through the software-defined radio platform to broadcast the signals.The simulation results show that the proposed algorithm can reach the accuracy less than 10 ns of predicting the signal transmission time and the Doppler frequency shift can reach less than 1 Hz,which verifies the invisibility and feasibility of this deception method.The physical experimental results show that the deception system can effectively perform timing/positioning/trajectory deception.The proposed method can achieve good concealment deception on software-defined radio platforms,with characteristics such as low cost,simple implementation,and minimal negative impact.关键词
