Abstract

This study investigates the adverse effects of geomagnetic storms on Global Navigation Satellite System (GNSS) positioning accuracy across South Asia, focusing particularly on Pakistan and neighboring regions. By analyzing ionospheric total electron content (TEC), scintillation indices, and GNSS positioning errors during geomagnetically disturbed days from 2010 to 2022, the research highlights significant degradation in positional reliability and satellite signal integrity. Using data from GNSS receivers stationed in Islamabad, Karachi, and Lahore, along with Dst and Kp indices, a clear correlation is established between geomagnetic disturbances and increased GNSS errors. This research has practical implications for aviation, telecommunications, and geospatial applications in the region.
