With phase structure function, a theory model could be constructed to describe the rate of total electron content index (ROTI) and its relationship with amplitude scintillation index \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$S_{4}$$\end{document}. The model is validated with measurements from GNSS array on short baseline. It is also found the effective scan azimuth angle \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\alpha_{{{\text{eff}}}}$$\end{document} with value of 25° could serve as threshold for effective \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$S_{4}$$\end{document} prediction from ROTI. Further analysis point out the effective scan speed \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$V_{{{\text{eff}}}}$$\end{document} and its ways passing through ionosphere determine the temporal and spatial sampling rate on irregularity, and when the different time separation for ROTI and \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$S_{4}$$\end{document} locates in the same range of phase structure function, the model could be extrapolated to predict S4 with ROTI measurements. The results suggest the possibility of using regular GNSS observations for scintillation monitoring.
