Abstract
In order to inhibit the degeneracy phenomenon in particle filter (PF) and the sample impoverishment caused by resampling, this paper proposes particle filter technology based on pseudo parallel genetic algorithm (PPGA-PF), in which PPGA improves PF. Theoretical analysis and computer simulation on PPGA-PF, PF and EKF in the Global Positioning System (GPS) show that filtering performance of the proposed technology has made apparent improvement.
