Abstract

Using the international ground-based network of two-frequency receivers of the GPS navigation system provides a
means of carrying out a global, continuous and fully-computerized monitoring of phase fluctuations of signals from
satellite-borne radio engineering systems caused by the Earth's inhomogeneous and nonstationary ionosphere. We
found that during major geomagnetic storms, the errors of determination of the range, frequency Doppler shift and
angles of arrival of transionospheric radio signals exceeds that for magnetically quiet days by one order of magnitude
as a minimum. This can be the cause of performance degradation of current satellite radio engineering navigation,
communication and radar systems as well as superlong-baseline radio interferometry systems.
