摘　　要：针对传统卫星定位欺骗算法在真实场景下真假信号并存环境下欺骗成功率低的问题,首先分析了真实场景下实现定位欺骗的条件;然后根据该条件,设计生成欺骗场景星历的算法,分近距远距两种情况进行了讨论,并分析了两种情况的适用条件;最后搭建实验系统进行了测试验证.测试结果表明,在真实场景下,近距、远距情况下均实现了卫星通道覆盖,位置、轨迹欺骗均获得成功.Aiming at the problem that the traditional satellite positioning spoofing algorithm has a low success rate of deception when true and false signals coexist in real scenarios,this paper first analyzes the condition of realizing positioning spoofing in real scenarios;and then accords to the condition to design the algorithm of generating the ephemeris of the spoofing scene,discussing the two cases of short distance and long distance,and analyzing the applicable conditions of the two cases.Finally,the paper sets up an experimental system to carry out the test verification.The results show that in real scenarios,satellite channel coverage is achieved in both short and long range cases,and that location and trajectory deception are both successful.
