Abstract:Instead of astronomical geodetic points, we proposed to put the baseline field, which has similar site conditions, forward. This paper analyzes the principle of starting from the observed error, then examines the measurement accuracy requirements and equipment selection. We use the GPS and industrial electronic theodolite in astronomical geodetic surveying and improve the methods of observation. After establishing the gyrotheodolite azimuth calibration device based on the baseline field, we do an experiment that shows that the accuracy can satisfy the specification requirements. Furthermore, the uncertainty analysis of the calibration device is given.
