| Abstract: | The carrier phase smoothing is generally used to reduce the influence of multi path effect and measurement noise in reginal area augmentation system，and only single frequency pseudorange observations are used in the divergence free smoothing.A smoothing scheme based on the linear combination of code measurement for redusing theinfluence of multi path effect，and improving the accuracy of Beidou code differential position，is proposed in this paper.The results calculated with the new method for real data was show that the position accuracy is significantly improved. |
| Keywords: | carrier phase smoothing local area augmentation code differential Beidou narrow lane combination |
