SPATIALLY-DISTRIBUTED SYSTEM OF RADIOELECTRONIC SUPPRESSION OF RECEIVING DEVICES OF USERS OF GLOBAL NAVIGATION SATELLITE SYSTEMS

摘要

FIELD: radio engineering and communications.;SUBSTANCE: invention relates to the field of radio engineering and can be used in the development of radio electronic suppression devices for receivers of users of global navigation satellite systems (GNSS), in particular, GNSS deployed on airplanes, cruise missiles, unmanned aerial vehicles, precision-guided weapon systems, etc. Spatially-distributed system for radio-electronic suppression of receiving devices of GNSS users includes a control point and remotely-controlled interference modules (IM), installed at a distance from each other, ensuring a continuous stay of the mobile GNSS user in the coverage area of at least one interference module, the control point and the IM being connected by a communication link. In addition, spatially-distributed system also includes sensors of physical fields integrated with the IMs, the outputs of which are connected to the control inputs of the IM and to the communication line, as well as sequentially connected sensors, a database containing the coordinates of IMs and physical field sensors, and an extrapolation unit determining the trajectory of the GNSS user's movement along the coordinates of the detected physical field sensors, the second input of the extrapolation unit being connected to the communication line, and the output – with the input of the control point, which additionally, taking into account the extrapolated trajectory of the GNSS user, includes the corresponding IMs in the emission mode and turns them off as the GNSS user moves.;EFFECT: technical result of the invention is to reduce the level of unintentional electromagnetic interference and energy costs by selectively incorporating the IMs, provided that GNSS users are detected.;1 cl, 1 dwg
