| Abstract: | We analyze the relationship between angle measuring error and aligning error of underground control network,and provide functional relation between angle measuring error and the length of each traverse using the least-squares fitting based on statistical information of angle measuring error. |
| Keywords: | angle measuring error stochastic model underground control network |
