| 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。

| Abstract: | 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 ofExperimental Building in Wuhan University in February 2013.Experimental results showed that when comparedto traditional least-squares,the improved Bancroft algorithm had the similar accuracy,and its computationalefficiency had been improved by 22%,which verified the feasibility and superiority of the improved Bancroftalgorithm in computation for SPP of dual positioning system. |
