摘　　要：为了提高全球定位系统GPS的定位精度和可靠性,提出了一种基于裂变自举粒子滤波FBPF的GPS定位系统算法。根据GPS输出的参数之间的相互联系建立了系统的状态方程,并应用于对GPS接收数据进行滤波处理的改进FBPF算法中。GPS导航系统中采用DSP对GPS接收机的输出信号进行译码和滤波处理。In order to improve the positioning precision and reliability of GPS, a filtering algorithm of GPS positioning system based on fission bootstrap particle filtering is proposed. According to the mutual relation of parameters outputted by GPS, the system state equations are presented and applied for improved fission bootstrap particle filtering algorithm carries on filtering deal for GPS receiver data. The DSP is used for decoding and filtering the outputting signals from the GPS receiver in GPS navigation system.
