METHOD FOR DETERMINING ERROR OF GEODETIC INSTRUMENTS FOR IRREGULARITY OF JOURNALS SHAPE AND SIDE BENDING OF TELESCOPE Russian patent published in 2016 - IPC G01C25/00 G01B11/26 

FIELD: surveying.

SUBSTANCE: method for determining error of geodetic devices for irregularity for journals shape and side bending of telescope includes fixing the reflecting mirror at an angle of 45° to axis of sight on the objective end of the test device telescope, arrangement the test device on the horizontal axis of telescope rotation. Reflecting mirror is oriented to deflect the axis of sight in direction, approximately parallel to the horizontal axis of the test device, and so that the mark image is in the field of view during telescope rotation around its axis. Then, the mirror is directed on the mark and its position relative to cross grid of the telescope are measured at different inclination distances of the telescope in reception at "circle left" and "circle right". Error is calculated according to obtained data.

EFFECT: technical result is decreased labor intensity, high reliability and accuracy of determining error of geodetic devices for irregularity for journals shape and side bending of telescope.
