Спутник навигационных систем. GPS 2R-9. [Редактировать]

GPS-2R (Global Positioning System) или Navstar-2R (Navigation System using Timing And Ranging) – третье поколение космических аппаратов системы GPS. GPS-IIR должны по контракту от 19989 года осуществить замену второго поколения аппаратов группировки. Производителем аппаратов выступает Lockheed Martin, которая использует для производства космический аппаратов свою коммерческую платформу AS-4000. Космические аппараты имеют трех-осевую стабилизацию и работают на 1572.42 MHz, 1227.6 MHz и 2227.5 MHz. Lockheed также отвечает за запуски аппаратов и их эксплуатацию. По сравнению с предшествующими аппаратами новое поколение спутников позволяет значительно улучшить точность определения координат на Земле.
