Study of options for constructing a low-orbit addition to the global navigation satellite system
Abstract
The possibility of using a low-orbit addition to the global navigation satellite system GLONASS based on small navigation spacecraft is being considered. In the class of delta systems, options and characteristics of orbital structures are defined, ensuring the specified requirements for the accessibility of the navigation field in relation to shading angles up to 25°. Estimates of the contribution of the considered variants of structures to improving the characteristics of the navigation field of the GLONASS orbital constellation were obtained.
- global navigation satellite system
- low-orbit addition
- spatial geometric factor
- navigation field availability

Исследование вариантов построения низкоорбитального дополнения глобальной навигационной спутниковой системы
Рассматривается возможность использования низкоорбитального дополнения глобальной навигационной спутниковой системы ГЛОНАСС на основе малых навигационных космических аппаратов. В классе дельта-систем определены варианты и характеристики орбитальных структур, обеспечивающих заданные требования по доступности навигационного поля применительно к углам затенения до 25°. Получены оценки вклада рассмотренных вариантов структур в улучшение характеристик навигационного поля орбитальной группировки ГЛОНАСС.
