The Gyro-Theodolite and its Value in, Modern Surveying Practice
A. Falter Falter Engineering Co., P.O. Box 1051, Sudbury, Ont.
Gyroscopic surveying instruments, which apply the physical law of a gyroscope, are being used for determining the azimuth of lines with a high degree of accuracy. In the past ten years, gyro-theodolites have been introduced widely for underground orientation in the mining industry of Russia, Germany and South Africa. Gyroscopic methods eliminate awkward procedures of conventional shaft plumbing, and provide more safety, excellent control and the highest precision at any point underground without interference with hoisting operations. The advantages of gyroscopic orientation in geodetic surveys become obvious in primary and secondary triangulation, in the determination of co-ordinates of single triangulation points, using the method of trigonometric resection and intersection, and when traversing over long •distances or in areas with obstructed view. Other fields of application are found in geophysical surveys and in the orientation of technical objects; e.g. radar stations, relay stations and ballistic missiles.
