Especially in the special risk operations which staff can not arrive to the difficult topographical conditions for surveying, the reflectorless total station can better show its functional advantages. Now, with the increasing of range which reflectorless total station can reach, the improvement in function, and to continue to intelligent direction, reflectorless total station uses more and more at home and abroad. Therefore, to understand and grasp the functional properties and the using methods of reflectorless total station is very important for us. This paper studied the reflectorless total station on the application, introduced the development, the features, and the prospects for development of reflectorless total station, introduced the structure and theory of its range knowledge, and through without the prism and have the precision of the intelligent non-reverberation total sta
