Abstract

In this article, the method of measuring the astronomical azimuth using an electronic total station, which is not intended for performing astronomical work, is considered. A method of measuring the astronomical azimuth using a high-precision electronic total station has been developed. Studies have been carried out to establish the influence of the components of errors in measurements of astronomical azimuth, forming the total budget of the error of the developed methodology, which has been tested on the reference stationary complex of metrological support of azimuth measuring instruments (СMS AMI).

Highlights

The Russian industry has not produced specialized theodolites and goniometers for astronomical measurements for more than twenty years
The obtained result of the astronomical azimuth using an electronic total station differs by no more than 1.5" from the azimuth obtained using the astronomical azimuth orientation system (AAAOS) installation, this is clearly evident from the results obtained, from which it follows that the developed technique is possible to use
Having analyzed the calculated measurement error of the developed methodology with the error obtained as a result of measurements (Table 1), it is possible to perform their comparative analysis by plotting a graph (Figure 10)

Summary

Introduction

The Russian industry has not produced specialized theodolites and goniometers for astronomical measurements for more than twenty years. The main way out of this situation is to maintain the existing fleet of astronomical measuring instruments in working condition and develop methods for performing astronomical measurements with existing modern geodetic measuring instruments that are not intended and not adapted for this type of work. Today the task of developing a specialized method of astronomical measurements for modern highprecision total stations is urgent. In this regard, a method for measuring astronomical azimuths was developed and tested using an electronic total station on a stationary complex of metrological support for azimuth measuring instruments (СMS AMI). The developed method allows using an electronic total station for measuring astronomical azimuth, and has a significant advantage over the classical method of measuring astronomical azimuth using an astronomical theodolite, due to the automation of measurement actions
