Description

The invention relates to the field of navigation and topographic referencing, in particular to methods for presenting and using digital topographic and geodetic information, and is intended to determine navigational and topographic and geodetic parameters for ground moving objects when solving tasks of topographic and geodetic support for combat operations of the Ground Forces units.

A known method of using a universal system of topographic location and navigation (patent RU No. 2487316 C1, B60P 3/00, 07/10/2013), adopted as a prototype. This method implements the display on the digital terrain map of the path and location of the moving object, loading in the on-board computer digital terrain maps of the SFX4 format from an external drive, automatic change of map sheets of any scale when the moving object goes beyond their border, automatic determination of the X coordinates on the digital terrain map , Y and the heights H of the points marked with the cursor of the operator.

The disadvantages of the method taken as a prototype are:

- the lack of the possibility of forming a specific area of work;

- the lack of the possibility of laying the proposed route of the NTS along the specified control points;

- the inability to save previously laid routes in the memory of the on-board computer;

- the lack of the ability to map additional objects;

- the lack of the possibility of forming a work area when it is impossible to use digital maps of the area;

- the inability to change the orientation of the digital terrain map;

- the inconvenience of working with digital terrain maps in various modes.

The invention solves the problem of increasing the effectiveness of topographic and geodetic support of the Ground Forces.

The technical result obtained by the implementation of the invention is to create a method of forming a mode of operation with digital maps of the area, providing in the conditions of use, including combat, loading into the on-board computer calculator of SXF4 format scales of 1: 25000, 1: 50000, 1: 100000, 1: 200000 via the Ethernet interface, forming a work area, if it is impossible to use digital terrain maps, forming a work area with a coordinate grid, displaying the location on the MSC of a moving object and its direction of movement, automatic change of CCM sheets of any scale when the coordinates of a moving object go beyond their border, laying of the proposed route of movement of a moving object at specified control points, storage previously dix route memory onboard computer, mapping additional objects, mapping coordinates X, Y and H points marked operator marker.

The specified technical result is achieved by the fact that in the proposed method of forming a mode of operation with digital terrain maps, including the ability to display on a digital terrain map the path and location of a moving object, loading digital terrain maps from an external drive into the on-board computer, automatically changing map sheets when a moving object exits beyond their border, automatically determining the coordinates and heights of points marked with the operator’s cursor on a digital terrain map, the new way is that on the formation of a regime for working with digital terrain maps additionally includes a number of operations aimed at expanding the possibilities of using the “Work with a map” mode: after loading digital terrain maps, it is possible to change the map scale both in the direction of increase and decrease; during operation, a function to hide or display a digital map of the area is implemented; during operation, it is possible to orient the map sheet in the direction of movement of the moving object or in the direction to the North; during operation, it is possible to center the map relative to a moving object, the current location of which is displayed in the center of the working window of the "Work with map" mode; when working, it is possible to lay several routes, which allows us to choose the optimal one based on the analysis of the cartographic situation; if it is impossible to use digital terrain maps, the grid mode for the area of work for which there is no map is used.

Providing the possibility of forming a work area, based on real conditions when performing tasks as intended, allows you to:

- to select the necessary cartographic material in advance, based on the task;

- pre-select the optimal scale of a digital map of the area;

- determine the number of downloaded files.

Providing the impossibility of using digital terrain maps, the formation of a work area with a coordinate grid allows you to:

- increase the combat readiness of the object of military equipment, which uses digital maps of the area, in extreme conditions;

- expand the possibilities of using the object of military equipment and its survivability.

Ensuring the laying of the proposed route of movement of the moving object at the given control points in an amount of at least 100 allows you to:

- with the necessary accuracy to plan the optimal route for the upcoming movement of a moving object;

- if necessary, edit the paved route.

Providing storage of at least 10 previously laid routes in the memory of the on-board computer allows you to:

- create a database of laid routes;

- effectively carry out the tasks as intended.

Providing the mapping of additional objects allows you to:

- in real time, monitor the operational situation in the area of work;

- create a local coordinate system associated with all elements of the weapons complex;

- provide geodetic information to the units of troops and individual units of weapons;

- increase the degree of automation of the preparation of source data for firing;

- increase the controllability and combat readiness of military units.

Ensuring the centering of the map relative to the moving object allows you to:

- provide a convenient overview of the information that appears in the working window;

- provide the maximum overview of cartographic information when working with digital maps of the area.

The orientation of the map in the direction of movement of the moving object or to the North allows you to:

- execute the compass on / off mode;

- track the angular position of the moving object relative to landmarks on the ground.

Technical solutions with features distinguishing the claimed solution from the prototype are not known 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 drawings, where in FIG. 1 shows the working window of the sub-mode "Work with the map"; in FIG. 2 - working window of the task “Route planning”; in FIG. 3 - working window for data entry; in FIG. 4 - working window of the task “Downloading maps”, in FIG. 5 - working window of the task "Formation of the area", in Fig. 6 - working window "Initial data"; in FIG. 7 - functional purpose of the buttons.

A method of forming a mode of operation with digital terrain maps is implemented as follows.

The “Working with a map” mode is designed to work with a MSC, determine the location (coordinates) of a moving object (PO) 1 on a digital terrain map (MSC) 2, and select a route of movement.

In the “Work with the map” mode, two sub-modes are possible: “March”, “Work with the map”. In the upper part of the working window 3, the control panel 4 with buttons 5 is displayed.

In the working window 3, against the background of MSC 2, the traveled route of software 1 is displayed.

To enlarge the scale of the MSC 2 sheet, click on the “Zoom in” button 6 on the toolbar 4, to reduce the scale of the MSC 2 sheet, click the “Zoom out” button 7.

During operation, you can temporarily hide or display the MSC 2 sheet, for this you need to click the "Hide / Show Map" button 8.

When the “Compass On / Off” button 9 is pressed, the top of the MSC 2 sheet is oriented in the direction of travel of software 1, and when the button is pressed, the top of the MSC 2 sheet is oriented to the North.

The sub-mode “March” is intended to display the current location and the route of movement of software 1 on the MSC 2. At the bottom of window 3, the following coordinates are displayed: current coordinates, altitude, directional angle, speed, distance traveled by software 1, the name of the area and the original scale of the sheet MSC 2, number sheets in the area, current time.

The sub-mode "Work with the map" is intended for downloading the MSC 2 files, forming the area of work, laying the route and removing signs of the operational situation. At the bottom of window 3, the coordinates of the position where the pointer is in the form of a crosshair 10, the current display scale of the MSC 2 sheet, the name of the area and the original scale of the MSC 2 sheet, the number of sheets in the area, and the current time are displayed.

When you bring the pointer 10 to any place on the MSC 2, to 1 or a sign of the operational situation, the coordinates of the place, object or sign are displayed in the bottom line of the window.

When you click the "Center the map relative to the object" button 11, the MSC 2 sheet is located so that the current location of the software 1 is displayed in the center of the working window 3.

To plot a route, click the “Route” button 12. In the window 13 that appears, enter the number of points necessary for laying a route. In the window 14, the coordinates of the point are entered and the “Next point” button is pressed 15. The input is repeated as many times as necessary. To return to window 13, you must click the button "Get a new route" 16.

To download the MSC 2, you must click the “Download maps” button 17, in the window 18 that appears, enter the path to the map files, click the “Mount” button 19, click the “View file list” button 20, select the classifier in rsc format and the corresponding ones in the list sxf files. Next, click the "Download maps" button 21. After the download of the MSC 2 is completed, the operational message "Download complete" appears.

To create the area of work for software 1, you need to click the button "Formation of the area of work" 22. In the window 23 that appears, click the button "View file list" 24. In the list of files downloaded by MSC 2, you must select two to four files and click the button "Generate area of work" 25.

If it is impossible to use CCM 2 in the area of work of software 1, a coordinate grid is formed. To do this, go to the working window 26 of the "Navigation" mode, the task "Initial data", select the directional angle "Manual entry" used. Enter the value of the directional angle in the range from 0 to 6000 DO and confirm the data entry ("Accept" button 27). Enter arbitrary values of the coordinates (Xн and Yн) of the area where there are no MSC 2. Go to the "Work with map" mode and control the appearance of the coordinate grid on the screen.

Thus, the invention solves the problem of achieving a technical result, which consists in creating a method of forming a mode of operation with digital maps of the area, providing in the conditions of use, including combat, loading into the on-board computer calculator of SXF4 format scales of 1: 25000, 1: 50000, 1: 100000, 1: 200000 via the Ethernet interface, forming a work area, if it is impossible to use digital terrain maps, forming a work area with a coordinate grid, displaying the location on the MSC of a moving object and its direction of movement, automatic change of CCM sheets of any scale when the coordinates of a moving object go beyond their border, laying of the proposed route of movement of a moving object at specified control points, storage previously dix route memory onboard computer, mapping additional objects, mapping coordinates X, Y and H points marked operator marker.
