Equatorial plasma bubbles (EPB), specifically anomalies in the ionosphere, have a substantial effect on the accuracy of Global Navigation Satellite System (GNSS) positioning. This study aims to examine the GNSS receiver signal’s inaccuracy in the presence of EPB over Biak (1.02\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$^{\circ }$$\end{document} S, 136\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$^{\circ }$$\end{document} E, 9.11\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$^{\circ }$$\end{document} dip lat.), Indonesia. We use GNSS data obtained from the Indonesian Continuously Operating Reference System (INACORS) to generate maps of the rate-of-total electron content (ROTI). These maps depict the occurrence of equatorial plasma bubbles (EPB). Likewise, we employ single-point positioning for a fixed station at Biak station, which is a part of INACORS, to determine the magnitude of positioning errors. Our study revealed that the GNSS signal exhibited a maximum positioning error of nearly 10 m with respect to the EPB, predominantly in the north-south direction.
