全站仪几乎可以用在所有的测量领域。电子全站仪由电源部分、测角系统、测距系统、数据处理部分、通讯接口、及显示屏、键盘等组成。
同电子经纬仪、光学经纬仪相比，全站仪增加了许多特殊部件，因此而使得全站仪具有比其它测角、测距仪器更多的功能，使用也更方便。这些特殊部件构成了全站仪在结构方面独树一帜的特点。
Total station can be used in almost all fields. Electronic total station by the power supply part, Angle measuring system, distance measuring system, data processing part, communication interface, and display screen, keyboard, etc.
Compared with the electronic theodolite, optical theodolite, total station increased a lot of special parts, which makes the total station has more than the other Angle, distance measuring instrument function, use more convenient also. These special components make up the total station unique characteristics in terms of structure.
