基于SVM的GPS有效性分析方法

Validity Analysis of GPS Signal Based on SVM

GPS定位在室外复杂环境下会受到影响,造成定位结果发散。针对GPS数据设计了一种基于SVM的GPS有效性判断,该方法突破了传统的GPS精度判断指标,创新地引入了其他GPS数据作为GPS有效性的指标,并提出了一种基于SVM的GPS信号的有效性进行分析判断。实验结果表明,该方法的GPS有效性判断准确率达到95.1%,剔除了无效的GPS信号。

GPS positioning will be affected in outdoor complex environments,causing the positioning results to diverge.Therefore,this paper designs a SVM-based GPS validity judgment for GPS data.This method breaks through the traditional GPS accuracy index and innovatively introduces other GPS indexes as an indicator of GPS effectiveness.The validity of a GPS signal based on SVM is purposed in this paper.The experimental results show that the accuracy of the GPS validity judgment of this method reaches 95.1%,and eliminates the invalid GPS signal effectively.
