Abstract

[Abstract]: The aim of this report was to examine the accuracy and limitations of automatic target recognition (ATR) in total stations through real-life field situations and obstructions. This was done by testing three total stations by reading through a series of obstructions to fixed prisms. Obstruction simulation templates were placed at various distances from the total station to obscure the view of the fixed prism. The prism was also placed at various lengths from the total station to assess the effect to distance. These results were then assessed and the different horizontal angle, vertical angle, and horizontal distance deviations were graphed and compared. The resulting deviations varied depending on the type and placement of the obstruction in front of the prism. After completing these experiments a set of field surveying recommendations was outlined for using ATR for electronic distance measurements. These recommendations will provide surveyors with important information designed to assist them in determining the accuracy of ATR readings in different obstruction environments.
