Description

The telescope and angle sensors of angular velocities are connected to the following tracks of the output channel, and, and the output of each angular velocity sensor is connected to the corresponding device: a light transducer unit.

FIG. 1 and 2 illustrate the essence of the present invention.

A two-axis astro-probe 3 is located on the telescope /, a) fixed in a biaxial rotary device on a movable base 2, designed to measure the angular mismatch of the object under study 4 from the optical axis of the telescope. Amplifier transducer blocks 5 serve for wonleys and re-transform: a total signal from an astro sensor and an angular velocity sensor block 6 mounted on a movable base in a separate biaxial m-turn device. The angular mismatch of the telescope is eliminated by the actuators of the mechanism. 7, according to the signals received by it, and from the amplifier-converter blocks.

Angle sensors 8 installed along the axles of the turntables of the telescope And the block of angular velocity sensors, together with amplifier 9 and 1 of the executive, and motors 10 installed along the axes of the turntable of the block of sensors of angular speeds, form a trace U | Drivers // matching axes of turn bearing units of the telescope and the unit of sensors of angular velocity.

In the initial state, the corresponding axes of the turntables of the telescope and the block of angular velocity sensors are parallel, which ensures the coincidence of the corresponding control axes and sensitivity axes of the angular velocity sensors.

The system works in the following way.

Before the start of the work, a rough initial orientation and stabilization is based on the selected object to be observed, and 2. After this, the telescope rotates in the reference-turn device and directs it to the object under study 4.

In the telescope pointing process, the following drives 11 synchronously rotate the angular velocity sensor block 6 at the same angles pointing over.

When the target is completed, when the optical axis of the telescope is directed to the object under study and the latter enters the field

The views of the astro sensor 3 and the axes of sensitivity of the angular velocity sensors are matched with the control axes of the telescope, the following drives are switched off and the system switches to the accurate stabilization mode. At the same time, in amplification conversion units 5, the error signals of the error signals generated by the astro sensor sum the output signals of the angular velocity sensor unit, proportional to the angular velocities of the explosives relative to the telescope control axes. This makes it possible to compensate for the speed error of stabilization and, consequently, to improve the accuracy of the system.
