Accuracy of determination of azimuth with a gyrotheodolite by the follow-up measurement

Abstract

The article deals with the determination of the achievable accuracy of an azimuth by the follow-up measurement, which is provided by the Sokkia GYRO X II automatic Gyro Station. The paper briefly describes basic information about the device and how it works. The first part describes the gyrotheodolite and the follow-up measurement, one of the methods of determining astronomical true north. Further, it describes the construction of a survey base station where the follow-up measurement was tested, followed by a procedure for measuring and subsequent data processing. Finally, the accuracy achieved is assessed.
