Description

The invention relates to the field of radio engineering and can be used in the development of electronic suppression (REP) of the receiving devices of navigation equipment of consumers of global navigation satellite systems (GNSS), in particular, placed on airplanes, cruise missiles, unmanned aerial vehicles (UAVs), in high-precision systems weapons, etc.

The known method of electronic radio electronic equipment (RES), based on the collection of data on the electronic environment and the formation of spatially distributed interference fields using small-sized interference transmitters (MPP) installed in the immediate vicinity of the suppressed RES [see, for example, Radzievsky V.G. A network-centric spatially distributed system based on small-sized intelligence and interference modules. - Radio engineering, 2012, No. 6, p. 4-11].

The disadvantage of this method is the low efficiency of suppressing the receiving devices of the navigation equipment of GNSS consumers, due to the fact that it is not possible to constantly maintain the close proximity of the interference source to a mobile object.

There is a method of creating intentional high-power radio interference to receivers of consumer navigation equipment placed on mobile devices operating on GNSS signals, based on the concentration of the total energy of a set of low-power radio interference transmitters distributed in space in a given area of space for a given time interval. In this case, the creation of deliberate high-power radio interference is ensured by the time-coordinate interaction of reconnaissance equipment and jamming stations [see, for example, patent RU No. 2563972, C1, IPC H04K 3/00, publ. September 27, 2015].

The disadvantage of this method is the presence of active reconnaissance means, which, firstly, are objects of counteraction from GNSS consumers, including weapons homing for radiation, and, secondly, they require coordinate-temporal interaction of reconnaissance means and jamming stations, which leads to the presence of unnecessary control links at the operational level under the action of reconnaissance aids and jamming stations in one zone.

Closest to the technical nature of the claimed invention is a method of receiving receivers of mobile GNSS consumers based on the formation of an interference field by spatially distributed small-sized interference transmitters [see, for example, http://chvvakush.ucoz.ru/publ/professionalnoe/aviatekhnika/ problemy_zashhity_gps_ot_pomekh / 10-1-0-27. Date reversed 04/13/2016].

The disadvantage of this method is the constant inclusion of all MPP, which leads to a complication of the electromagnetic environment for their own consumers of GNSS and RES for other purposes, as well as to unjustified energy costs.

The technical result of the invention is the elimination of these disadvantages.

The specified technical result is achieved by the fact that in the known method of REP receiving devices of GNSS consumers, based on the formation of an interference field by spatially distributed MPPs, according to the invention, using these changes in the physical fields created by mobile GNSS consumers, these mobile consumers are detected and include MPP for radiation, extrapolated the motion paths of mobile GNSS consumers, if necessary, include additional MPPs, and turn off as GNSS consumers move after turning on cheniya next WFP.

The essence of the invention lies in the fact that using changes in the physical fields created by mobile GNSS consumers, they are detected and turned on by MPP for radiation, extrapolate the motion paths of mobile GNSS consumers and, if necessary, include additional MPPs, and turn off as GNSS consumers move after switching on another MPP .

It is known that when moving GNSS mobile consumers, physical fields (acoustic, seismic, electromagnetic, electrostatic, magnetic, gravitational, etc.) change, which can be used to detect mobile GNSS consumers. So, for example, in an article by Geister S.R. and Jackie A.M. “Solving the problem of detecting low-altitude apparatuses using acoustic and seismic fields” [Science and Military Security, No. 1, 2008, p. 42-46] shows the process of occurrence of acoustic and seismic fields during UAV flight and the possibility of detecting an unmanned aerial vehicle using acoustic and seismic sensors. Such sensors can be integrated with MPP. When approaching the MPP of the mobile GNSS consumer, the sensor is triggered and the MPP is turned on for radiation, the GNSS consumer's receivers will be suppressed.

The problem of extrapolating the trajectory of the mobile consumer GNSS can be solved by the results of detection at a ground control point similar to the problem solved, for example, in patent RU, 2463622, C1, IPC G01S 13/58, publ. 10.10.2012, the inclusion of additional MPP can be performed on the basis of analysis, for example, the direction of movement of the GNSS consumer and the MPP coordinates. Thus, the radiation MPP are included only when the object of suppression appears. Small-sized interference transmitters are turned off as the GNSS consumer moves after the next MPP is turned on.

This achieves the technical result indicated in the invention.

The method can be implemented, for example, as follows.

Preliminarily, spatially distributed MPPs are installed on the ground with integrated sensors for changing physical field parameters at a distance of 10-15 km from each other, providing a continuous GNSS consumer in the coverage area of at least one MPP [see, for example, http: //chvvakush.ucoz .ru / publ / professionalnoe / aviatekhnika / problemy_zashhity_gps_ot_pomekh / 10-1-0-27. Date reversed 04/13/2016]. Their coordinates are entered, for example, in the database of the ground control point (NPU). When the sensor is triggered (detection of a GNSS mobile consumer), they turn on the MPP for radiation and transmit information via the communication line to the NPP, where, taking into account the MPP coordinates, the received information is analyzed. During the analysis, the following tasks are solved:

- extrapolation of the trajectory of the mobile consumer GNSS;

- Definitions of WFP located in the direction of movement of the GNSS mobile consumer.

If necessary, with NPU include on the radiation MPP located in the direction of movement of the mobile consumer GNSS. Thus, continuous suppression of the receiving devices of mobile GNSS consumers is ensured. Small-sized jammers are switched off as the GNSS consumer moves after the next MPP is turned on.

This achieves the technical result indicated in the invention.
