JAMMING DEVICE Russian patent published in 2014 - IPC H04K3/00 

FIELD: radio engineering, communication.

SUBSTANCE: known device, having a receiving and a transmitting path, series-connected reference generator and amplifier, further includes series-connected spacecraft signal delay calculating path and clock signal generating path, wherein the first group of data inputs of the spacecraft signal delay calculating path is the adjustment bus of the device, N spacecraft signal generating paths, an adder and a digital-to-analogue converter, the output of which is connected to the data input of the transmitting path, the reference input of which is combined with the reference input of the receiving path, the output of the amplifier and the reference input of the clock signal generating path, the output of which is connected to clock inputs of the N spacecraft signal generating paths, the adder, the digital-to-analogue converter and the spacecraft signal delay calculating path, the n-th group of data outputs of which, where n=1, 2, …, N, is connected to the group of data inputs of the n-th spacecraft signal generating path, the first and second groups of data outputs of which are connected to corresponding groups of data inputs of the adder, the first and second groups of data outputs of which are connected to corresponding groups of data inputs of the digital-to-analogue converter, and the second data input of the spacecraft signal delay calculating path is connected to the data output of the receiving path.

EFFECT: distortion of navigation parameters for radio navigators of a group of users located in a spatially confined but known region.
