METHOD AND DEVICE FOR CREATING DELIBERATE JAMMING OF SATELLITE GLOBAL POSITIONING SYSTEM Russian patent published in 2024 - IPC H04K3/00 

FIELD: defence devices.

SUBSTANCE: invention relates to protection of objects from unmanned aerial vehicles (UAV) by setting up deliberate radio interference to a NAVSTAR satellite global positioning system (NAVSTAR GPS). After registration of signals of NAVSTAR GPS satellites and their frequency selection by frequency ranges L1, L2, L5, in each of three frequency channels, each of which corresponds to its frequency range L1, L2 or L5, selected frequency signal L1, L2 or L5, respectively, is demodulated on the corresponding channel carrier frequency L1, L2 or L5, converted into digital form, its recurrence period is determined and recorded in the register, then, the signal repetition period is increased as compared to the input satellite signal, the satellite signal frequency L1, L2 or L5 corresponding to the channel is modulated, amplified and, continuously repeated, emitted by the antenna of the interfering station as an interfering signal.

EFFECT: increasing the efficiency of interference effects on the onboard sensors of the NAVSTAR GPS of UAV.
