METHOD AND DEVICE OF DETERMINATION OF COURSE OF OBJECT Russian patent published in 2009 - IPC G01C21/18 

FIELD: physics; measuring.

SUBSTANCE: invention concerns to the measuring technics and in particular, to resorts of precision determination of a course of object at the control of an error of development of a course systems of navigation of the ship at its finding at a mooring. Technical effect lies in increase of a measurement accuracy of a course of object. Thus the first theodolite is ashore and second on the ship. Theodolites measure an angle of rotation of the ship during determination of its course using gyrotheodolite and further are considered at its determination. In dependent points of the formula of the method offered to spot a slope angle of the ship for same time and to measure a corner of intertwisting of an installation site of the first theodolite concerning an installation site of the gyrotheodolite and to consider at determination of a course of the ship. The device includes gyrotheodolite, erected in interior premises of the ship so that optical communication with marking devices of a diametric plane of object is provided and in addition in the device are included: the first theodolite mounted outside of object and mechanically related with it, a reference point, or the second theodolite, erected ashore, thus a theodolite erected on object, is optically related to a reference point or with the second theodolite, the measuring instrument of rolling of object and the controller, thus an exit of a measuring instrument of rolling is joined to the first inlet of the controller on which second inlet data from an exit of the gyrotheodolite move, and the controller exit is connected either to the display, or to the central computer of object. In dependent points of the formula of the device it is additionally included a measuring instrument of a corner of intertwisting. As a measuring instrument of rolling the navigating resort of object can serve.

EFFECT: increase of measurement accuracy of a course of object.
