Abstract:
This article describes organization of operational monitoring of the ionospheric parameters in a local region using the results of multifrequency GNSS-measurements. The purpose of monitoring is to determine the critical frequency of the F2 layer and the height of the maximum of the F2 layer in real time. The refined by using the measured values of the total electron content IRI ionosphere model has been used to calculate the values of the critical frequency of the F2 layer and the height of the F2 layer maximum. Total electron content is obtained by phase GNSS measurements taking into account the effect of both GNSS receiver and satellites inter-channel delays. Refining the IRI model is done by calculating the refined values of the solar activity index for each moment of time. The considered approach of the ionospheric parameters operational monitoring organization in a local area has been implemented in the hardware and software solution. Verification of the obtained values of the F2 layer critical frequency and maximum height is carried out by synchronous measurements of the hardware and software solution for monitoring the ionospheric parameters and the vertical sensing ionosonde.
