Abstract. At the end of 2020, in order to solve the problems of metrological support of existing and perspective azimuth measuring instruments a stationary Complex of Metrological Support Tools of Azimuth Measuring Instruments (CMST AMI) was developed in FSUE “VNIIFTRI”, which forms the part of the state primary special standard of location coordinates.
During the state tests of the state primary special standard of location coordinates, the study of metrological characteristics in terms of measurements of astronomical azimuth was conducted. In the process of research, a measurement error model was developed, describing the constituent parts and components influencing on the azimuthal measurements of the standard.
At present, such researches were performed for the first time, have great theoretical and practical impact and are also relevant due to the extensive use of azimuthal measurement results in many industries.

Keywords: non-excluded systematic error, astronomical azimuth, stationary complex of metro­lo­gical support tools of azimuth measuring instruments, state primary standard of location coordinates.
