🔷Abstract l 摘要
In view of the limitation of the difference method, the adjustment model of CPⅢ precise trigonometric leveling control network based on the parameter method was proposed in the present paper. The experiment results show that this model has a simple algorithm and high data utilization, avoids the negative influences caused by the correlation among the data acquired from the difference method and its accuracy is improved compared with the difference method. In addition, the strict weight of CPⅢ precise trigonometric leveling control network was also discussed in this paper. The results demonstrate that the ranging error of trigonometric leveling can be neglected when the vertical angle is less than 3 degrees. The accuracy of CPⅢ precise trigonometric leveling control network has not changed significantly before and after strict weight.
