Method and device for target seeking for geodetic devices

摘要

A method for target seeking in geodetic survey measurements comprises the steps of generating at least a first light bundle by a measurement device from a light source arranged therein, the light bundle periodically pivoting back and forth or revolving about the standing axis of the measurement device and fanning out in the vertical plane and being sent to at least one receiver arrangement arranged in at least one target station arranged at a distance from the measurement device. The steps of the method also include generating an electrical signal when the light bundle hits the receiver arrangement of the at least one target station, conveying these electrical signals generated in the target station, or the time difference determined from these electrical signals to the measurement device through a transmitting device provided in the target station, determining the horizontal angle to the respective sighted target station from the time difference of two electrical signals generated one after the other in time by angles measured or stored at constant time intervals and pivoting a second modulated light bundle at an angle in the vertical plane and sending it in the direction of the target station for determining the vertical angle of the measurement device. Further, when the second light bundle hits the receiver arrangement in the target station, the method includes the step of generating another electrical signal and sending it to the measurement device and determining the vertical angle to the respective target station therefrom in the measurement device. Also disclosed is a device in accordance with the method.
