Abstract
The effect of high geomagnetic activity on the positional error in GPS signal by considering five geomagnetic storms events of different intensities during December 2006 has been studied. The main conclusions drawn from the study are that during all the five geomagnetically disturbed days the positional error increases significantly. During all the events increase in the latitudinal error is more than the longitudinal error. Study further records that in most of the events the increase in both the errors usually occurs during the main phase of the storm. The scatter of the 2D positional error around the actual position was also found to be large during all the events. However, scatter of error was found be larger along the longitude than the latitude. The scatter of 2D latitudinal positional error in meters was found to be larger than the longitudinal error. The error points are within the confidence level before the onset of geomagnetic storm event and move significantly out of the 95% error eclipse and error circle.
