陀螺全站仪是利用高速回转体的内置陀螺进行真北方向的准确定位的高精度定向仪器,可以不依赖其他条件就能够测定真北方向。仪器常数的稳定性直接影响到定向结果的可靠性。针对该问题,文章从仪器常数探讨了陀螺定向的精度问题,总结了影响仪器常数稳定性的因素。提出了在使用陀螺全站仪前应对仪器进行检测、认真观测并计算零位值的建议。
The gyro total station is a high-precision directional instrument that uses the built-in gyro of a high-speed revolving body to accurately position the true north direction. The true north direction can be measured independently of other conditions. The stability of the instrument constant directly affects the reliability of the directional result. In order to solve this problem, this paper discusses the problem of gyro orientation accuracy from the instrument constant, and summarizes the factors that affect the stability of the instrument constant. Proposed in the use of gyro total station instrument to deal with the detection, careful observation and calculation of zero-value recommendations.
