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…
Traveling wave packets of total electron content disturbances as deduced from global GPS network data
E. L. Afraimovich, N. P. Perevalova, S. V. Voyeikov
We identified a new class of mid-latitude medium-scale traveling ionospheric disturbances (MS TIDs), viz. traveling wave packets (TWPs) of total electron content (TEC) disturbances…
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…
Estimating the contribution from different ionospheric regions to the TEC response to the solar flares using data from the international GPS network
L. A. Leonovich, E. L. Afraimovich, E. B. Romanova +1
This paper proposes a new method for estimating the contribution from different ionospheric regions to the response of total electron content variations to the solar flare which us…
