ABSTRACT:
A method and apparatus for remote control surveying which eliminates the need for a rod man or other assistant while performing surveying operations with an electronic distance measuring device. The method includes positioning reflectors over the end points of a base line of known length, positioning an electronic distance measuring device over a desired survey station, rotating the reflectors into alignment with the electronic measuring device by remote control, and measuring the distance from the survey station to the two reflectors. The method also includes traverse operations using a single reflector positioned over a base point. The location of the survey station can then be calculated and the electronic distance measuring device may be relocated to subsequent survey stations and the reflectors realigned by remote control. The apparatus includes an attachment for a standard surveyor's tribrach which rotatably supports a standard reflector unit and an electric motor in a vertical position. An operator selectively activates switches on a portable radio transmitter. The signal is received by a control box which energizes the motor to rotate the reflector unit in the desired direction. A stroboscopic light may be attached to the top of the reflector unit to rotate in conjunction with the reflector unit and aid in its alignment.
