В статье описываются особенности построения алгоритма трехмерной томографии концентрации электронов в ионосфере по радиосигналам глобальной навигационной спутниковой системы. На модельных данных исследуются положенные в его основу алгебраические методы реконструкции. Обсуждаются способы учета априорных сведений и подходы к оптимизации параметров этих алгебраических методов. Приводятся экспериментальные результаты реконструкции ионосферы по данным спутниковой системы точного позиционирования Республики Беларусь.

The paper describes the design of an algorithm for three-dimensional radio tomography of electron concentration in the ionosphere based on the GNSS data. Simulation data are used to describe the algebraic reconstruction techniques underlying the algorithm design; also considered are the methods taking into account a priori information as well as the approaches to optimization of parameters of these algebraic methods. The results of the experimental ionospheric reconstruction obtained with the use of the data obtained from the satellite system of precise positioning of the Republic of Belarus are presented.
