The cyclical activity of the solar spot reaches its peak every 11 years, and the solar burst at this moment discharges a large amount of corona matter and its consequential solar burst causes disturbance of the earth’s magnetic field. At this time, the ionospheric value also changes, which becomes the contributor to arousing an error by producing the delay in GPS signal. This study worked out the positioning error quantitatively in an effort to grasp the influence of the larger-scale solar burst, which occurred due to the activity of the solar spot, on the analysis of GPS positioning. In addition, this study grasped the influence the activity of the solar spot on our country using Kp index and TEC map, and suggested that there occurred a maximum deviation of about 37cm from the standard data at a specific time by processing the GPS measurements at hourly intervals. It is predicted there will be the maximization of the sunspot activity in the future, so it’s necessary to definitely take such an influence into consideration in analyzing GPS positioning.
