【摘要】：本论文归纳总结了陀螺全站仪/经纬仪的发展历史、分类和国内外的研制状况。在分析了自由陀螺的两个基本特性和进动规律的基础上，研究了地球自转对摆式陀螺仪的作用及其主轴相对地球的运动轨迹，从而解释了陀螺仪寻北的基本原理。进一步明确了定向测量中的陀螺北方向、坐标北方向和真北方向的关系，总结了定向测量中的6种观测方法。比较了逆转点法和中天法两种定向方法的优缺点。本论文通过实验研究了环境温度、振动、纬度和磁场对GP3130R3陀螺全站仪定向精度的影响。通过实验得出了这些因素对GP3130R3陀螺全站仪定向精度的影响规律和函数模型。在实际的定向作业中，，根据外业环境加入各种改正，对定向的精度有显著的提高。通过实验测试了GP3130R3陀螺全站仪的稳定性。悬挂带弹性稳定性、动量矩稳定性和零位稳定性均符合规范要求。本论文设计了针对GP3130R3陀螺全站仪的精度评定方案，结合玉龙校区的GPS静态控制网对其进行了内符合精度和外符合精度的分析，结果在其标称精度范围内。本论文设计了数据处理软件，能及时检查定向数据是否符合限差要求，自动输出定向成果表，使内外业几乎同时间完成，提高了工作效率。
[Abstract]:This paper summarizes the development history , classification and development of the gyro total station / theodolite . Based on the analysis of the two basic characteristics and precession laws of the gyro , the basic principle of the earth ' s rotation on the pendulum gyroscope and its relative earth motion are studied . The relationship between the north direction , the north direction and the true north direction of the gyro in the directional measurement is further clarified . The advantages and disadvantages of the reversal point method and the middle - day method are compared .

The influence of ambient temperature , vibration , latitude and magnetic field on the directional accuracy of GP3130R3 gyroscope ' s total station is studied experimentally .

In this paper , the accuracy evaluation scheme for the GP3130R3 gyro total station is designed , and the accuracy and the accuracy of the external coincidence are analyzed in combination with the GPS static control network of Yulong campus , and the result is within the range of its nominal accuracy .

This paper designs the data processing software , can check whether the directional data meets the requirements of the limit difference in time , automatically outputs the directional results table , makes the internal and external industries almost the same time , and improves the working efficiency .
