Mining gyrotheodolite

Feb 02, 2021

Dec 18, 2021 In surveyinga gyrotheodolite also: Theodolites are used mainly for surveying applications, and have adapted for specialized purposes such as meteorology. In surveyinga gyrotheodolite also: Due to their precision, gyroscopes are used in gyrotheodolites to maintain direction in tunnel mining. An initial approximate estimate of the meridian is needed
