Research on GNSS Interference Localization Method Based on Navigation Data
Interference with the Global Navigation Satellite System(GNSS),a crucial communication tool,can result in significant financial losses and adverse social effects.Thus,the influence of ground interference must be swiftly eliminated in order to guarantee the quality of satellite communication services.Traditional ground interference monitoring and location techniques have problems of limited mobility,numerous constraints,high costs,etc.In this paper,a GNSS interference localization method based on satellite navigation data is proposed.It employs a light UAV to carry satellite navigation data acquisition equipment,analyzes GNSS signal quality in real time,and synchronously adopts a combination of small-area multi-point omnidirectional monitoring and multi-point directional approximation to achieve high-precision localization of ground interference.The method has the advantages of low cost,high efficiency and wide application scenarios.
