Description

The invention relates to geodesy, in particular to methods for geodetic training of combat missile forces and artillery of the ground forces.

The well-known "Textbook of the sergeant of the missile forces and artillery of the ground forces" for commanders of topographic and geodetic departments and topographic detachments, book 4, approved by the commander of the missile forces and artillery of the ground forces, edited by V.V. Burov (p. 4-8).

The textbook sets out the basics of topogeodesic training for combat missile forces and ground artillery - a way to create a basic artillery (local) network, i.e. the set of fixed points fixed on the ground, which are created as the initial basis for topographic reference of the elements of the battle order of the missile forces and artillery and the preparation of the initial data for firing.

Topographic and geodetic training of missile forces and artillery includes:

- creation of an initial basis for topographic and geodetic reference;

- topographic and geodetic reference of positions, points, posts.

The initial basis for topographic and geodetic reference (geodetic networks and catalogs of coordinates of geodetic points, topographic and special maps, aerial photographs with a coordinate grid) is created in advance in peacetime and wartime, as well as directly during military operations.

Surveying networks include:

- State Geodetic Network (GHS);

- special geodetic networks (GHS).

The state geodetic network is created according to a unified plan at the state level and is the basis for compiling topographic maps and performing geodetic measurements. Data on GHS points are placed in catalogs that contain the following information: name of the point indicating the type and height of the outer sign, point class, full rectangular coordinates, absolute height, directional angles of directions to landmark points and other geodetic points with the names of these points and distances to them.

GHS are created on the basis of GHS points in the areas of deployment of troops in order to ensure their actions. For each GHS point, its coordinates, directional angles of the network sides and directions to landmark points are determined.

GHS points on the ground are fixed by permanent or temporary centers and are indicated by external signs. Data on GHS points are placed in the lists of coordinates, which are compiled for each position area.

In addition to creating the initial basis, an integral part of topographic and geodetic preparation is topographic and geodetic reference of positions, points, and posts, which includes: determination of the coordinates and heights of positions, points, and posts and determination of directional angles of reference directions.

The coordinates of the points to be tied and the directional angles of the reference directions are determined using instruments with respect to points and directions of geodetic networks.

The disadvantages of this method of creating a support artillery (local) network of topographic and geodetic divisions and topographic units, taken as a prototype, are:

- high error in determining the parameters of local geodetic networks;

- high time costs when conducting topographic and geodetic reference;

- the impossibility of ensuring the functioning of high-precision weapons systems;

- the need to use a large number of topographic and geodetic calculations for combat support of large units of troops;

- the need for a large number of control measurements to ensure the required accuracy;

- low level of technical equipment used in the topozapryazchik.

The proposed invention solves the problem of increasing the efficiency of topographic and geodetic support of the ground forces.

The technical result obtained by the implementation of the invention is to create a method for the automated formation of local geodetic networks of high accuracy, in which a set of automated measures is taken to determine the topographic and geodetic data of points of local geodetic networks with constant or periodic correction of the navigation system using satellite navigation or optical means accordingly, with the possibility of transmitting the results to objects a tomatizirovannoy command and control system.

The specified technical result is achieved by the fact that in the proposed method for the automated formation of local geodetic networks of high accuracy class, which includes determining, using a navigation system (NS) coordinates, directional angles to the orientation directions of points of local geodetic networks, fixing the data on the ground permanent or temporary centers, compiling lists of coordinates for each positional area with further topographic and geodetic linking of positions, points, posts, n The main point is that when creating local geodetic networks (LGS) at the initial stage, the initial orientation and determination of the ground vehicle (STS) initial coordinates are carried out autonomously by a set of on-board equipment with further input of the initial data to the on-board STS calculator both manually and automatically, at the second stage, the area of work is formed where the LGS should be created, for which a package of digital maps is downloaded locally to the on-board computer from an external device ty (MSC) and the necessary files are selected from the MSC, at the third stage, the route is laid on the MSC in accordance with the proposed configuration of the LHS, at the fourth stage the NTS is moved in accordance with the laid route, during which the coordinates of points of the created LHS are automatically determined, points If necessary, LGS are fixed on the ground by centers with external signs and additional landmarks and special conditions of the route condition are determined for them, to improve accuracy the NS projection according to satellite navigation equipment (ASN) data, or during short-term stops of the NTS using landmarks with known coordinates, at the fifth stage, geodetic data of points on the MSC marked by the operator cursor are automatically determined to thicken the LGS points, at the sixth stage, data is generated on the generated LGS in print or electronic form with the possibility of their automated transmission via communication channels to objects of the automated command and control system (ASUV).

Performing at the initial stage in the autonomous mode the initial orientation and determination of the initial coordinates of the NTS with a set of on-board equipment with further input of the values of the initial data into the on-board calculator of the NTS both manually and automatically:

- allows you to fully utilize the benefits that have the means of satellite navigation;

- to maintain the autonomy of the navigation system in the absence for one reason or another of signals from navigation spacecraft;

- speed up the process of preparing for the creation of a local topographic and geodetic network.

The formation at the second stage of the work area where the LGS should be created allows:

- determine a sufficient set of files with the MSC necessary to complete the task;

- if necessary, perform additional loading of cards or their removal.

At the third stage of the operation, the route laying on the MSC in accordance with the proposed configuration of the LGS allows, based on the analysis of a specific area of the area according to the MSC, to select the optimal route for obtaining for a minimum time and at the lowest cost of topographic and geodetic information sufficient to generate the LGS.

Implementation at the fourth stage of the NTS movement in accordance with the route laid allows you to:

- get the most complete basic and additional topographic and geodetic information;

- get information about the area that is not on the map of the area;

- to form a reference system for LGS points.

Correction of the NS according to satellite navigation equipment (ASN), or during short-term stops of the NTS using landmarks with known coordinates, allows you to:

- maintain high accuracy in determining topographic and geodetic data throughout the movement along the laid route;

- To obtain generally high quality data for all LGS items.

At the fifth stage, the automatic determination of geodetic data for points on the MSC marked with the operator cursor allows you to:

- receive operational topographic and geodetic information about any point or object on the MSC located in the area of ongoing work;

- get the required density of LGS points.

Presentation at the sixth stage of data on the generated LGS in print or electronic form with the possibility of their automated transmission via communication channels to objects of the automated command and control system (ASUV) allows you to:

- to provide interacting units with cartographic material marked with LGS points;

- ensure the operation of the NTS, equipped with a navigation system, as part of an automated troop control system.

Technical solutions with features distinguishing the claimed solution from the prototype are unknown and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

The invention is illustrated by the drawing, which shows the algorithm for implementing the method of automated formation of local geodetic networks of high accuracy class.

The method of automated formation of local geodetic networks of high accuracy class is implemented as follows.

1. When creating an LGS at the initial stage, the initial orientation and determination of the initial coordinates of the NTS are carried out autonomously with a set of on-board equipment with further input of the values of the initial data into the on-board computer (BV) 2 NTS both manually and automatically.

To carry out initial orientation in offline mode, the directional angle of the longitudinal axis of the NTS is used, determined using NS 1 NTS and automatically entered into the on-board computer (BV) 2. To increase the accuracy of determining the directional angle, the mode can be used with an increased determination time.

To solve navigation problems, the directional angle of the longitudinal axis of the NTS can be used, determined with the help of the sight (B) 3 installed on the NTS, followed by manual data entry into BV 2.

For offline determination of the initial coordinates, the coordinates obtained from ASN 4 are used.

2. At the second stage, the area of work is formed where the LHS should be created, for which a package of digital terrain maps (MSC) 5 is downloaded to the on-board computer from an external device and the necessary files are selected from the MSC 5.

To download MSC 5 from an external device (WU) 6, it is necessary to download information from a disk with MSC 5 files in sxf format in BV 2. To form the area of work of the STC, you need to view the list of files loaded MSC in which you need to select from two to four files.

3. At the third stage, the route is laid on MSC 5 in accordance with the proposed configuration of the LGS.

When laying a route, the pointer to MSC 5 selects the starting point. Next, the pointer points to the next route points, while neighboring points will be connected by straight lines, together forming a line of the laid route 7. To continue laying the route, the pointer is installed at the end point of the laid route and then the next points of the route are marked with an indicator. Work with TsKM 5 on laying the route is possible only in the parking lot.

4. At the fourth stage, the movement of the NTS is carried out in accordance with the route laid, during which the coordinates of the points of the created LGS are automatically determined, the points of the LGS are fixed on the ground with centers with external signs 8, and additional landmarks and special conditions of the route’s condition are determined for them, for to improve accuracy, NS correction is performed according to satellite navigation equipment (ASN) 4, or during short-term stops of the NTS using landmarks with known coordinates osredstvom reticle 3 mounted on the NTS.

During the movement of the NTS in the working window of the BV 2 against the background of the MSC 5, the current coordinates, altitude, direction angle, speed, the distance traveled by the MTS, the name of the area and the original scale of the sheet of MSC 5, the number of sheets in the area are displayed. During operation, you can temporarily hide or display the MSC 5 sheet, and also, if necessary, orient the MSC 5 in the direction of the NTS movement. In other cases, MSC 5 focuses on the North.

Correction NS 1 according to ASN 4 is performed continuously during the movement of the NTS. If for some reason there are no signals from space navigation devices, short-term stops of the NTS are used to correct the NS 1 using landmarks with known coordinates.

5. To thicken the LGS points in the fifth stage, the geodetic data of the points on MSC 5, marked with the operator’s cursor, are automatically determined.

6. At the sixth stage, the data on the generated LGS are presented in print or electronic form with the possibility of their automated transmission via communication channels to the objects of the automated command and control system (ASUV) 9.

Moreover, the printing reproduction of the cartographic material can be carried out both with the help of a printing device (PU) 10 located on the NTS, and using similar means located on the ASUV 9 objects.

When the NTS is included in the ASUV 9 information exchange system with the ability to provide missile forces and artillery (RV and A) subsystems with ASUV 9 high-precision information about the coordinates of characteristic terrain points, directional angles of landmark directions, the coordinates of control points of the laid routes, it can significantly reduce the combat training time of troops .

Thus, in the present invention, the problem is solved to achieve a technical result, which consists in creating a method for the automated formation of local geodetic networks of high accuracy class, in which a complex of automated measures is taken to determine the topographic and geodetic data of points of local geodetic networks with constant or periodic correction of the navigation system using tools satellite navigation or optical means, respectively, with the possibility of transmitting results obtained objects of the automated command and control system.
