FIELD: geodetic instruments. SUBSTANCE: repeat referencing of telescope of geodetic level I to geodetic beacon 3 or geodetic levelling rod 4 is performed with same installation of geodetic level with its turn through 180 deg and break of its collimating ray through 180 deg via optical reflecting element 2, for instance, prism placed in front of objective lens of telescope I of geodetic level. EFFECT: improved functional precision. 4 cl, 5 dwg
