摘　　要：提出了一种改进的Bancroft算法运用于组合双系统SPP解算。为检验新算法的解算精度,选取2013年2月采集于武汉大学实验大楼楼顶的GPS/BD双频双模接收机实测数据进行解算。实验结果表明改进的Bancroft算法与传统的最小二乘算法的解算精度相当,其解算效率与最小二乘算法相比提高了22%,从而验证了改进的Bancroft算法在组合双系统SPP解算中的可行性及优越性。An improved Bancroft algorithm was proposed to be applied in computation for single point positioning（ SPP） of dual positioning system. To verify the computational accuracy of the improved Bancroft algorithm,GPA/BD receiver measured data of dual-band and dual mode had been used,which were collected at the roof of Experimental Building in Wuhan University in February 2013. Experimental results show ed that when compared to traditional least-squares,the improved Bancroft algorithm had the similar accuracy,and its computational efficiency had been improved by 22%,which verified the feasibility and superiority of the improved Bancroft algorithm in computation for SPP of dual positioning system.
