Спутник технологический. DART. [Редактировать]

Данный космический аппарат создан для испытаний в полете аппаратуры и программного обеспечения, необходимых для автономного сближения на орбите и маневрирования в окрестностях цели – инспекция МКА MUBLCOM. МКА создан на базе четвертой (дополни-тельной) ступени РН Pegasus XL, известной как «Гидразиновая вспомогательная двигательная система» HAPS (Hydrazine Auxiliary Propulsion System). Ступень считается интегральной частью аппарата и располагается сзади. Передняя часть именуется платформой прибора AVGS. Она включает в себя систему реактивного управления, аккумуляторы и связную аппаратуру и несет собственно аппаратуру AVGS. В бортовую систему навигации и управления входят компьютер фирмы SBS Technolo-gies, модульный блок авионики собственного изготовления, инерциальный измерительный блок (Honeywell) и многоканальный приемник спутниковой навигационной системы GPS с четырьмя антеннами (Surrey Satellite Technol-ogies Ltd). Многочисленные функции осуществляет бортовое программное обеспечение ARPO (Autonomous Rendezvous and Proximity Operations). «Сердцем» ARPO является программа-менеджер миссии, которая работает на «среднем» уровне автономности. Менеджер способен обработать многие нештатные ситуации, пропустить отдельные действия и поменять их порядок, чтобы выполнить задание в целом. Программа просчитывает многие тысячи вариантов работы и выбирает тот, который позволяет достичь поставленных целей с учетом всех ограничений. В ARPO реализованы различные типы маневров в окрестностях аппарата-цели с учетом законов небесной механики, а также алгоритмы «силового» подхода по любой линии. В функции программного обеспечения ARPO входит также построение «запретных сфер» вокруг КА-цели и выполнение маневра увода в том случае, если угрожает столкновение. МКА солнечных батарей не имеет и питается только от литий-ионных аккумуляторов (шесть по 50 А час, два по 9 А час) компании SAFT. Ступень HAPS имеет азотный бак на 5,77 кг и шесть двигателей подсистемы ориентации ACS – газовых сопел с тягой 5,67 или 11,34 кг – которые обеспечивают трехосную ориентацию МКА во время орбитального полета и управление по каналу вращения при работе ЖРД. Управление по тангажу и рысканью осуществляется и путем несинхронного включения гидразиновых двигателей.
МКА оснащен двумя видеокамерами компании Ecliptic Enterprises:

  • Прибор AVGS (Advanced Video Guidance Sensor – перспективный датчик видеонавигации) изготовлен подразделением Advanced Optical Systems и предназначен для работы в замкнутом контуре управления аппаратом.
  • Корпус платформы AVGS изготовила компания Vermont Composites. Платформа имеет собственную двигательную установку - сис-тему реактивного управления RCS. В нее входит бак рабочего тела (азот) емкостью 31,75 кг (в т. ч. 30% резерва) «и 16 газовых сопел компании MООG тягой 0,37 кг и удельным импульсом 60 с.
