Abstract:

Miniaturization of the satellite navigation receiver is the development trend in the future. The characteristics of attacking for the satellite navigation receiver network are analyzed. Since it is difficult to accurately position and correct the interference with the traditional wireless sensor network (WSN) interference detection method, an algorithm based on the improved angle of arrival(AOA) positioning mechanism for the attack detection is proposed. And then a hyperbolic positioning algorithm is put forward based on the principle of satellite navigation system for deception jamming single interference sources to locate the interference sources. Finally, the experiment by using the algorithm is conducted. The result shows that the attack detection and correction efficiency are very high.
