This paper focus on disturbance occurring in ionosphere due to certain phenomena’s like solar flare Coronal Mass Ejection(CME),Sudden Ionospheric disturbances(SID),sunspots etc. The observation from VLF receiver is the keystone for numerous experiments, studies and results on Earth’s ionosphere. The Sun is capable of producing strong radio emission which may directly affect the wireless communication and navigational system without any warning. Using recent techniques different equipment’s can be builtto accomplish these observation using a unified hardware and software. To detect the real time condition of ionosphere, SDR technique and Gnu Radio framework is used.
