Degradation of signals and operation failures of radio engineering satellite systems during geospace disturbances accompanied by abrupt changes in the geomagnetic field
E. L. Afraimovich
During strong magnetic storms, the errors of determination of the range, frequency Doppler shift and angles of arrival of transionospheric radio signals exceeds the one for magneti…
Isolated ionospheric disturbances as deduced from global GPS network
E. L. Afraimovich, E. I. Astafieva
We investigate an unusual class of medium-scale traveling ionospheric disturbances (MS TIDs) of the nonwave type, isolated ionospheric disturbances (IIDs) that manifest themselves…
Testing of the transionospheric radiochannel using data from the global GPS network
E. L. Afraimovich, V. A. Karachenschev
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 mo…
Degradation of GPS performance in geomagnetically disturbed conditions
E. L. Afraimovich, V. V. Demyanov, T. N. Kondakova
The GPS performance is impaired in conditions of geomagnetic distrubances. The rms error of positioning accuracy increases in the case where two-frequency GPS receivers of three ma…
A case study of the mid-latitude GPS performance at nighttime during the magnetic storm of July 15, 2000
E. L. Afraimovich, O. I. Berngardt, O. S. Lesyuta +2
Using the geomagnetic storm of July 15, 2000 as an example, we investigated the dependence of GPS navigation system performance on the nightside at mid-latitudes on the level of ge…
Ionospheric response to the total solar eclipse of June 21, 2001
E. L. Afraimovich, O. S. Lesyuta
We discuss the measurements of the main parameters of the ionospheric response to the total solar eclipse of June 21, 2001. This study is based on using the data from three station…
