The feature of deception jamming for GNSS-dot networks is researched and analyzed,and it is difficult to accurately locate and correct the interference position by using the interference detection methods of the traditional WSN,a new attack detection algorithm that based on an improved angle of arrival（AOA） positioning mechanism to determine the point of disruption and interference correction is proposed.Nextly the algorithm of a single interference source localization based on the hyperbolic method by using anti-jamming principle of the GNSS is researched and given,and can locate both single and multiple interference sources.Then the indicators and methods of performance evaluation for the GNSS-dot networks are proposed.Finally,Experiment based on the algorithm is realized,and the attack detection and correction is very efficient,and interference location under ideal conditions is higher efficiency,and the strategies of anti deception jamming are also identified.
