滑窗检测的GNSS/INS抗欺骗新方法
A New GNSS/INS Anti-spoofing Method Based on Consistent Sliding Window Detection
摘要
Abstract
Given the problem that it is difficult to identify the gross errors and spoofing signals of GNSS/INS loose combination system,an anti-spoofing method based on the consistency detection of the sliding window was pro-posed.This method consists of two parts including deception detection and deception resistance.Firstly,according to the characteristics of continuous transmission of spoofing signals,a sliding window was introduced to improve the existing position consistency detection methods and further realize reliable detection of spoofing signals.Then,for the integrated navigation system with different precision inertial navigation system,when the autonomous navigation was interfered by spoofing signals and the spoofing signals can be detected,its performance was analyzed.Based on it,the corresponding resistance strategies were put forward.Finally,five simulation situations were designed to verify the proposed method.The experimental results show that the proposed method can be used to correctly iden-tify the accidental gross errors and spoofing signals,and the corresponding strategies can be adopted to verify the effectiveness of the proposed method.关键词
