FIELD: the invention refers to the field of astrometry.
SUBSTANCE: the mode is contained in the following: heavenly bodies are observed with registration of the moments of Greenwich time of passing of the heavenly body through a lateral visor flatness, parallel to the flatness of the meridian and removed from it on a known angular distance, and also through the flatness of the meridian and corresponding zenithal distances are measured. At that spherical triangles are formed and at solving them desired magnitudes are determined. For realization of the mode a meridian circle is used, before its objective three mirrors are installed for making two images of the heavenly body and for creation of a lateral visor flatness parallel to the flatness of the meridian.
EFFECT: provides absolute astronomical definitions.
