INS辅助的PMF-FFT快速捕获算法
Research on Fast Acquisition Algorithm Based on PMF-FFT with INS-Aided
摘要
Abstract
Aimed to acquire the GNSS signal faster,PMF algorithm and its parameters setting are analyzed. PMF-FFT algorithm with INS-aiding is adopted,which narrows the 2-D search range substantially. To improve acquiring performance of the algorithm,the weighted means by Window function is employed,then,the algorithm performance is analyzed. Experimental results show that the method with INS-aiding greatly decrease average acquisition time. The PMF-FFT algorithm with the Windows is more effective than traditional algorithms.关键词
