电磁波测距仪已在全国许多部门普遍采用。水利水电工程大部分修建在山区,高程测量的任务十分艰巨。由于采用电磁波测距仪可使距离测量相对简化,测距精度、速度均有显著提高;经纬仪竖盘采用自动调平,天顶距测量速度、精度亦相对提高,因此,电磁波测距仪在水利水电系统的使用范围也将越来越广泛。关于电磁波测距仪进行三角高程测量精度的研究,有关专家均有精辟论述,对生产单位
Electromagnetic wave range finder has been widely adopted in many parts of the country. Most of the water conservancy and hydropower projects built in the mountains, the task of elevation measurement is arduous. Because of the use of electromagnetic range finder can make the distance measurement is relatively simplified, ranging accuracy, speed are significantly improved; theodolite vertical plate with automatic leveling, zenith distance measurement speed, accuracy is also relatively improved, therefore, electromagnetic range finder in water conservancy The scope of use of hydropower system will also be more extensive. On the electromagnetic range finder Triangle elevation measurement accuracy of the experts have brilliant insight on the production unit
