На основе анализа особенностей навигационно-временных определений и методологических основ проектирования в системах высокоточного позиционирования проведена генерация вариантов спутниковой радионавигационной системы, исходным шагом в которой является синтез её базового варианта. Рассмотрены наиболее эффективные процедуры разрешения неоднозначности фазовых измерений, основанных на избыточности фазовых измерений, а также процедуры, заключающиеся в целочисленной максимизации функции неоднозначности, выбранной из характера периодичности сигналов навигационного космического аппарата. Сформулирован критерий точности позиционирования. Based on the analysis of the features of navigation-time definitions and methodological foundations of design in high-precision positioning systems, the generation of options for a satellite radio navigation system was carried out, the initial step in which is the synthesis of its basic version. The most effective procedures for resolving the ambiguity of phase measurements based on the redundancy of phase measurements, as well as procedures involving the integer maximization of the ambiguity function, selected from the nature of the periodicity of the signals of the navigation spacecraft, are considered. A criterion for positioning accuracy is formulated.
