LabVIEW developed by National Instruments is a graphical programing tool based on the data flow. Due to its characteristics, the recent years it is an ideal tool for both design and implementation of embedded software. This paper presents the development of LabVIEW based Real time GUI system for the studies of variations of percentage of occurrence of VHF amplitude scintillation characteristics using radio beacon signals of 250.649 MHz transmitted from FLEETSAT satellite positioned at 73 o E longitude received over near equatorial station Anantapur(14.7 o N, 77.7 o E, Dip angle 15.4 o N). Already real time digital recording system isexisted, but the disadvantage with the system is inability of the graphical representation of amplitude scintillation patches. Hence , an attempt has been made to overcome this problem with the help of LabVIEW based GUI system for the amplitude scintillations suitable to have data compatibility with Excel and Origin graphical packages for further analysis of the Ionospheric irregularities Scintillation Index (SI),effect of Geomagnetic storms and power spectral variations with amplitude scintillations. The developed system is implemented and executed successfully.
