| 摘 要： | 在精密单点定位中，通常假定接收机差分码偏差(Differential Code Bias，DCB)被钟差吸收，而不去单独进行考虑，从而可能影响最终的定位精度。为了验证DCB对定位精度的影响，针对2019年1月1日BJFS站一天的观测数据，用Bernese软件进行数据解算，并分是否考虑DCB影响的两种情况进行实验。结果表明，在考虑DCB影响后精密单点定位的收敛速度及定位精度得到明显提高，定位精度达厘米级。

| Abstract: | In precision single point positioning, Differential Code Bias(DCB)of receiver is generally assumed to be absorbed by clock difference rather than considered separately, which may affect the final positioning accuracy. In order to verify the influence of DCB on positioning accuracy, Bernese software is used to solve the data according to the observation data of BJFS station on January 1, 2019. The results show that the convergence speed and positioning accuracy of precise point positioning are significantly improved after considering the influence of DCB, and the positioning accuracy reaches centimeter level. |
