Спутник связи. Iridium NEXT 111. [Редактировать]

Компания Iridium Communications Inc. анонсировала в июне 2010 что она собирается полностью обновить свою орбитальную группировку космических аппаратов связи. В этой связи она заключила контракт с Thales Alenia Space относительно разработки и производства космических аппаратов нового поколения. При этом, компания Orbital ATK была выбрана в качестве подрядчика по работам связанным со сборкой и испытаниями изделий. Согласно планам компании, будущая группировка должна будет включать 72 космических аппарата на орбите и девять которые будут находиться в резерве на Земле. Стоимость работ по обновлению не разглашалась, однако, исходя из данных производителей можно ориентировочно определить стоимость работ в размере 2.9 млрд. долл. 
С технической точки зрения каждый из аппаратов в качестве основной полезной нагрузки должен будет иметь на своем борту фазированную L диапазонную антенну, которая будет способна генерировать около 48 лучей, которые будут покрывать круг диаметром около 4700 км. Также на аппаратах установлен Ка диапазонный ретрансляционный комплекс который будет осуществлять как сброс информации на Землю, так и осуществлять передачу информации между аппаратами на орбите. 
Помимо основной задачи связанной с передачей информации аппараты компании позволяют устанавливать на борт дополнительную полезную нагрузку общей массой до 50 кг и потребляемой мощностью до 90 ватт. К настоящему времени известно, что на борт аппарата планируется устанавливать:

  • Полезную нагрузку компании Aireon LLC, которая предназначена для организации контроля за воздушным трафиком.
  • 58 аппаратов должны будут оснащены системами AIS которые должны будут позволить отслеживать суда в режиме реального времени.
