Abstract
The accuracy and dependability of the Global Positioning System (GPS) can be severely
impacted by severe space weather occurrences. This work explores the measurement of GPS
variability during such situations using the Dilution of Precision (DOP) metric. The diurnal
fluctuation of DOP under quiet space weather conditions was determined by analyzing GPS data
collected during a selected severe space weather event. According to findings, there was no
noticeable increase in DOP values during the severe space weather event, which suggests that the
sources where I obtained the data did not register the geomagnetic storm event. Throughout the
event, the pattern of diurnal fluctuation is also disturbed. The results show that DOP is a useful
tool for evaluating GPS variability and emphasize the significance of taking space weather
effects into account when evaluating GPS performance. The findings of this study have
consequences for GPS users and operators, especially in situations when high accuracy and
reliability such as navigation, precision agriculture, and emergency response.
