Abstract

Based on the results of the analysis of coordinate data obtained as a result of constant registration at the Mikhnevo Geophysical Observatory of IDG RAS using a stationary GPS receiver, it is shown that during periods of strong geomagnetic disturbances, the positioning error increases significantly. It is shown that the variations of the positioning error in magnetic storms are characterized by a well-defined periodicity with a period of about 3 minutes. In this case, the maximum error is contained in the range of 4 ‒ 26 m and practically does not depend on the amplitude of the geomagnetic variation. The data obtained in this research allow us to consider the variations of the positioning error as an indicator of the disturbed state of the ionosphere and atmosphere during magnetic storms, as well as as a parameter that characterizes the degree of disturbance of the environment and the conditions for the propagation of a high-frequency electro-magnetic GPS signal in it.
