Abstract: When radio waves pass through the ionosphere, the amplitude and phase of the signals change irregularly, and this phenomenon is called ionospheric scintillation. The main parameters that indicate the event are S4 and ɸ60. In this project, the data obtained by GPS receiver can be logged and processed automatically by programming in C++. C++ is the main programming method with MATLAB and LabVIEW involved as well. The “autotrigger” C++ program reads the ISMR file and computes the value of S4 and ɸ60. Then, the two parameters are compared with the threshold and the one to trigger the file is chosen. Once the parameter is greater than the threshold, the trigger file will be executed. The program is used to trigger automatically. Meanwhile, by modifying the C++ program “RecorderTestApp” on the DTA devices, the configuration and connection are realized and the equipment can start recording.
