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…
The evolution of three-dimensionally localized vortices in shear flows. Linear theory
I. G. Shukhman, V. B. Levinski
The evolution of a small-amplitude localized vortex disturbance in an unbounded shear flow with the linear velocity profile is investigated. Based on the exact solution of the init…
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…
