SOURCES OF ERRORS IN ANGLE MEASUREMENT AND MEASUREMENT OF ANGLES BY THE METHOD OF CIRCULAR SETS

This article discusses the sources of errors that occur during angle measurement in geodetic and topographic works, as well as the principles of measuring angles using the circular acceptance method, also known as the Struve method. The paper highlights both instrumental and observational errors, along with techniques to minimize them. The Struve method, which allows for more accurate determination of horizontal angles by using double observations from two circle positions, is explained in detail. The importance of precision and error correction in geodesy is emphasized.
