A set of simulation system of GNSS vulnerability environment

which provides integrated simulation of interference in GNSS signal transmission link

which includes GNSS electromagnetic interferences

atmospheric electromagnetic environment

fault in space link is designed.The system mainly consists fault simulator of space system

deception/barrage jamming devices

signal simulators related software of atmospheric model.The system realizes simulation test under interference scenes of the GNSS system different vulnerability

and generates interference RF signal output.Designs scheme of main system modules is focused on

experimental analysis and effect display is carried out using corresponding modules

experiments show that each module is effective

and the system scheme is feasible.
