摘要
陀螺经纬仪的定向精度是评价其质量的重要指标之一。以GAK-1型陀螺仪为例,从其定向过程中主要的误差来源入手,理论上对陀螺经纬仪定向过程及影响测量精度予以研究与探讨,并结合赵家寨煤矿现场生产实践,实例分析了陀螺经纬仪的定向精度,提出了提高其定向精度与工作效率的意见与建议。
Orientation accuracy of gyrotheodolite is one of the important indexes for quality assessment. Taking the GAK - 1 gyrotheodolite as an example, from main origin of errors in the middle of orientating, research is carried on process of orientation and influence survey accuracy in theory. In combination with production practice, orientation accuracy is analyzed in example, and suggestions are proposed to improve orientation accuracy and working efficiency.
