NAVIGATION SYSTEM RADIO-FREQUENCY SIGNAL SIMULATOR Russian patent published in 2014 - IPC G01S7/40 

FIELD: radio engineering, communication.

SUBSTANCE: simulator has a drive generator, series-connected signal distributor, pseudorandom sequence generator, multiplier connected to the output of the pseudorandom sequence generator, the output of the multiplier being connected to a modulator, the second and third inputs of the multiplier are respectively connected to an information code sensor and a pseudorandom sequence bit error generator, the input of which is connected to the second output of the signal distributor, the second output of which is connected to one of the inputs of the information code sensor; the simulator also includes a function generator in form of series-connected binary code-to-unitary code converter, digital integrator and phase changer, a motion law code sensor, an information bit error generator, an initial phase setting unit in form of series-connected single pulse sensor and delay unit, wherein the motion law code sensor is connected to the input of the binary code-to-unitary code converter, a discrete phase changer is connected between the output of the drive generator and the input of the signal distributor, the output of the delay unit is connected to the second input of the pseudorandom sequence generator, the input of the information bit error generator is connected to the second output of the signal distributor and the output is connected to the second input of the information code sensor.

EFFECT: broader functional capabilities.
