Аннотация: Представлены результаты исследований изменчивости ионосферных задержек и сравнительной эффективности их компенсации с использованием сетевого дифференциального метода ГНСС-позиционирования в различные времена года. Показано, что в осенне-зимний период недоучтенная ионосферная задержка при одночастотном дифференциальном позиционировании может достигать 0.3 м на базовых расстояниях до 35 км и 0.9 м на базовых расстояниях до 150 км, а в весенне-летний период ее величина уменьшается в 2-3 раза. Использование дополнительной авторской методики сетевой дифференциальной коррекции ГНСС-наблюдений позволяет в значительной мере (на 30—40 %) уменьшить остаточные ионосферные задержки и повысить точность позиционирования.

| Ключевые слова: глобальная навигационная спутниковая система (ГНСС), дифференциальная сетевая коррекция, ионосферная задержка, точное позиционирование. |
