Abstract EN
We have used numerical simulation to study the effects of ionospheric irregularities on accuracy of global navigation satellite system (GNSS) measurements, using ionosphere-free (in atmospheric research) and geometry-free (in ionospheric research) dual-frequency phase combinations.
It is known that elimination of these effects from multifrequency GNSS measurements is handi-capped by diffraction effects during signal propagation through turbulent ionospheric plasma with the inner scale being smaller than the Fresnel radius.
We demonstrated the possibility of reducing the residual ionospheric error in dual-frequency GNSS remote sensing in ionosphere-free combination by Fresnel inversion.
The inversion parameter, the distance to the virtual screen, may be selected from the minimum of amplitude fluctuations.
This suggests the possibility of improving the accuracy of GNSS remote sensing in meteorology.
In the study of ionospheric disturbances with the aid of geometry-free combination, the Fresnel inversion eliminates only the third-order error.
To eliminate the random TEC component which, like the measured average TEC, is the first-order correction, we should use temporal filtering (averaging).
