陀螺定向对提高贯通横向精度的效果研究

Research on the Effect of Gyrostatic Orientation on Improving the Accuracy of Horizontal Breakthrough Survey

对某贯通导线中不加测陀螺边和加测陀螺边分别进行了贯通误差预计,从陀螺定向技术提高贯通横向精度的理论出发,计算了贯通横向精度的提高率,为贯通测量中加测陀螺边的位置与数量的确定提供了理论依据。

This paper predicts respectively the breakthrough errors of the surveys with additional gyro-side and without additional gyro-side,and starting from the theory of improving the accuracy of horizontal breakthrough accuracy with gyrostatic orientation technology,calculates the increasing rate of horizontal breakthrough accuracy,which provides the theoretical references for the determination of the location and quantity of additional gyro-side in the breakthrough survey.
