These operations are usually carried out by one operator, and the collimation work by the telescope, the keyboard operation after checking the display of the surveying instrument main body, and the display of the data collector are checked. However, there is a serious problem that it is necessary to continuously perform three tasks of keyboard operation, which lengthens the working time and lowers the working efficiency.

Therefore, the emergence of a surveying system that can save labor in these three tasks and improve the efficiency of surveying tasks has been strongly desired.
