Description

(54) yniOjNJEPHOE US The invention relates to a gyroscopic instrument. There are portable eyeglasses for the earth gyrocompass containing pzhlb to the reading device between the rotary to the fixed body of the gyrocompass in combination with the autocollimator on the rotary body and the specular reflector of light on the sensitive element. The disadvantage of this design is its complexity. In addition, it does not allow binding to the source or oriented direction in the process of the camcorder compass, which increases the time for determining the azimuth and does not allow it (. To control the position of the axis viewer during the start-up process to avoid accidental errors The circuit of the invention is inferior to the design of the device and the shortening of the measurement time. For this, in the device being designed, the “1aaqn & light” is made with several facets, which are located in a partially faceted GID CT. IN FOR A GROUND PASA iriJi-rfivibi and parallel to the axis of the main element. On the first floor there is a design of a ground-based gyro compass circuit with a vertical bend angle device. 4 1tribor rigidly mounted autocollima) Lyon tube 5, having a grid with a scale from the focal plane. A rigidly fixed Gfism 6 with mirror edges is fixed on the SE, with this norm: al X one of the faces may 6i, iTb is parallel to the axis of the gyro-motors. Each face of the Ymalaya prism is equipped with a Shuosky optical mirror reflecting the light of the light source 7 and allowing the subglome to measure the angle of rotation of the sensitive element on a scale of light inside a tube within its ps: view. When using one of the serial photo lenses as an objective lens, it is possible to measure the angles of rotation of the sensitive element but one face of the mirror ds 1, i.e., many; gra; 1 on the prism must have 20-30 facets; . Cor; C 2, having an upper clip of the torsion suspension, is mounted in the bearing 8

to ensure rotation within 360 °. The sighting device 9 provides sighting on the ground regardless of the position of the SE.

When working, the equipment is installed so that the image of the mark coincides with the crosshair of the grid of the sighting tube. Rotation of the housing 2 in the bearing 8 sets the axis of the gyro engine near the meridian. In this case, the angle of rotation is measured using an autocollimation tube fixing the passage of each face in front of the lens. In order not to count the number of past faces, you can install a scale 10 on the body 2, indicating only the number of the face in front of the lens of the autocollimation tube, and take the face facing north to be the initial one (O).

Such a scale, without complicating the design of the device, will make it more convenient to use. 25 After the acceleration of the gyro engine and razarretirovani-SE on the scale of the autocollimation tube, the points of reversal of the precessional oscillations of the SE are observed and the position is equal to the weight of the SE.

The gyroscopic azimuth of the oriented side is calculated by the formula

The position of the balance of SE, during the start-up process, that is, when observing the precession oscillations of the sensitive element, the observer can control the position of the sighting axis, which eliminates the possibility of a random error and reduces the process of intentions.

Claims (1)

Claims The ground angle goniometer IHpoKOMiiaca contains an autocollimator, a light source located on the body of the gyrocompass, and a mirror light reflector rigidly attached to the body of a gyrocompass, characterized in that, in order to simplify the design, the core of the gyrocompass, in order to simplify the design, reduce the length of the unit and reduce the body length of the gyro. It is made with several faces, which are located similarly to the faces of a regular multi prism and are parallel to the axis of suspension of the sensitive element.
