Description

The utility model relates to the field of measurement technology, in particular to gyroscopic instruments, radio navigation, topography, and can be used for orientation on the ground - determining the azimuths of directions and coordinates, solving geodetic problems, etc.

At present, a device for determining azimuth and location is known: US Pat. RU 178904 U1 Ros. Federation: IPC 2006.01 G01C 1/00; G01S 19/13 / I.V. Chernov; applicant and patent holder I.The. Chernov. - No. 2017137539; declared 10/26/2017; publ. 04/23/2018, Bull. No. 12 (hereinafter prototype). The device contains a gyro block and a tacheometer movably connected to it, forming a gyrotheodolite, while satellite geodetic equipment is additionally introduced, containing a receiver of two or more GPS / GLONASS frequency signals and a satellite antenna, which is coaxially integrated in one housing with a gyrotheodolite. The prototype device allows you to determine azimuths with an accuracy of the order of 0.0000097-0.000015 rad (up to 2-3 arc seconds), however, it has a significant drawback for solving geodetic problems: connecting the gyro unit to a total station (theodolite) in one housing, which increases azimuth acquisition time (geodetic reference of directions is performed outside the time of gyroscopic determinations); reduces the reliability of obtaining the azimuth and its accuracy (the mechanical effect of the observer during measurements on the device’s body as a result of which its displacement occurs).

The objective of the device for determining the azimuth of direction and location (hereinafter the device) (Fig. 1) is to determine the coordinates of the installation point and azimuth. The technical result is: reducing the time to determine the azimuth; increasing the reliability of orientation and increasing the accuracy of determining the azimuth of the direction up to 0.0000097 rad (up to 2 arc seconds); joint determination of the coordinates of a point and azimuth of a direction; ensuring ease of use during operation by placing the device and its components in a compact housing and eliminating the total station (theodolite) from the device.

The problem is solved in that, in contrast to the prototype device, the structural element is eliminated - a tacheometer (theodolite).

The housing is made in the form of a multi-volume structure, consisting of several elements. Element 1 comprises a receiver of two or more frequency signals of radio navigation systems and a corresponding satellite dish. Element 2 is connecting and provides alignment 1 with 3 (6 - the axis of the device). Element 3 - gyro block. Unlike the prototype device, the device does not have a total station (theodolite). Also, the device is supplemented with an autocollimation mirror - 4.

The device operates as follows.

The device is installed near one of the points fixing the oriented direction, it is horizontal on the tripod platform - 5. Data from satellite systems are received by satellite geodetic equipment 1, where they are converted to location data. The value of geodetic latitude B is used by gyro block 3 to determine the direction of the astronomical meridian N. The location data and N specify the orientation of the plane of the autocollimation mirror 4. The geodetic reference of the oriented direction from the plane of the autocollimation mirror 4 is performed during gyroscopic determinations.

In the claimed device, a new technical solution is implemented in comparison with the prototype device: the structural element - total station (theodolite) is abolished; added structural element - auto-collimation mirror; Measuring information is transmitted via a cable connection in series: satellite geodetic equipment - a gyroblock and is converted. The application of the proposed practical solutions can reduce the time to obtain the azimuth; to increase the reliability and accuracy of determining the geodetic azimuth compared to the prototype device up to 0.0000097 rad (up to 2 arc seconds); jointly determine the coordinates of the point and the azimuths of directions; to ensure ease of use during operation by placing the device and its components in a compact housing and the abolition of the structural element - total station (theodolite).

This utility model is industrially applicable when performing geodetic work (determining the coordinates of points and azimuths of directions).
