Function: recording to
electronic memory of satellite radio signals at the frequencies of 150
MHz and 400 MHz at the receiving points along the meridian Spitsbergen
archipelago – Kola Peninsula – Moscow – Rostov – Voronezh region –
Sochi. Sampling frequency is 50 Hz. The receivers detect
radio signals in the VHF-UHF range transmitted from Russian navigation
satellites. When passing through the ionosphere, the signals undergo
transformations, which depend on the ionospheric structure.
Simultaneous registration of satellite signals by all receivers of the
array provide their phase and amplitude in the points of ray crossing
and reconstruct of the electron density distributions in the vertical
plane above the array by means of tomographic inversion.
