精调系统 meaning in English

fine regualtion system

In this dissertation , we studied the tcra1101plus total station position system , which introduced the principle and characters of the instrument ' s closed loop tracking system . also we explained the cause of prism ' s position error and brought forward mathematic model to correct , moreover , the good results has been drawn form the expenriments . the kinetic survey system have been realized , which the sampling rate attain more than 5hz and the position precision can be less than 2mm on condition that targeted - point moving slowly at the velocity below 2cm / s . having finished the survey system to examine whether the fine - tuning stewart platform in good status , we have finished mensurating the position reference of the fine - tuning stewart platform and the offset of the prism
在此基础上研制了多台仪器在线控制高频采样动态跟踪测量系统，采样率大于5hz ，在跟踪小于2cm / s低速运动目标时，测量精度好于2mm ；完成对馈源二次精调系统的检测，包括对二次精调平台位置基准的标定和观测棱镜偏心差的测定；设计不同动态测量实验，对全站仪动态跟踪的误差来源和特点进行了分析；从实验角度，对全站仪的测量时滞及其稳定性进行了测试分析，给出了定量的结果；比较了全站仪和计算机的内部时间系统，发现两者存在较大差异。
