Спутник навигационных систем. Navstar 68. [Редактировать]

КА был изготовлен на предприятии компании Boeing Defense Space and Security (Эль-Сегундо, шт. Калифорния) и был доставлен в шт. Флорида 26 февраля 2013 года. Корпорации Boeing заказана сборка серии из 12 КА модели GPS-2F. Три из них уже находятся на орбите, в том числе запущены: первый – КА GPS-2F-1 ракетой «Дельта-4» 28 мая 2010 года, второй – КА GPS-2F-2 ракетой «Дельта-4М+» 16 июля 2011 года, третий – КА GPS-2F-3 ракетой «Дельта-4 RL-1082» 4 октября 2012 года.

По заявлению представителей корпорации Boeing, у них есть возможность поддерживать оставшиеся космические аппараты модели GPS-2F, чтобы запустить до трех спутников в течение одного года, если потребуется для функционирования системы. Расчетная продолжительность эксплуатации КА модели GPS-2F составит, по данным ВВС, до 12 лет. Эти спутники являются более точными и менее восприимчивыми к помехам, чем КА GPS предыдущего поколения. На новых спутниках будет также задействован оперативный гражданский сигнал L5, который используется коммерческой авиацией, а также в интересах поисково-спасательных операций.

Запуск очередного, пятого по счету, спутника GPS-2F-5 предварительно запланирован на октябрь 2013 года.
