Спутник ДЗЗ. Envisat 1. [Редактировать]

Cпутник, построенный Европейским Космическим Агентством для исследования Земли из космоса. На момент середины 2007 года являлся и является до сих пор самым крупным спутником, запущенным Европейским космическим агентством (ЕКА).На борту Энвисат несёт девять инструментов, собирающих информацию о суше, воде, льде и атмосфере, используя различные способы измерения.

Полезная нагрузка:

  • ASAR (Advanced Synthetic Aperture Radar) наблюдает Землю в микроволновом спектре от 4 до 8 ГГц. Этот инструмент позволяет отслеживать изменение высоты поверхности с субмиллиметровой точностью. 
  • MERIS (MEdium Resolution Imaging Spectrometer) — спектрометр, исследующий свет, отражаемый Землёй (поверхностью и атмосферой). Основная цель спектрометра — изучать цвет океана, например для того, чтобы дать оценки концентрации хлорофилла и твёрдых частиц. 
  • AATSR (Advanced Along Track Scanning Radiometer) измеряет температуру морской поверхности. 
  • RA-2 (Radar Altimeter 2) — радар, наблюдающий два электромагнитных диапазона: Ku-диапазон и S-диапазон (2-4 ГГц); служит цели изучения океанской топографии, наблюдения за льдом и измерения высот суши. 
  • MWR (Microwave Radiometer) измеряет количество водяного пара в атмосфере и содержание жидкой воды в облаках. 
  • DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) — микроволновая следящая система, выполняющая задачу точного позиционирования спутника. 
  • GOMOS (Global Ozone Monitoring by Occultation of Stars) наблюдает за звёздами сквозь атмосферу Земли; по изменению их цвета можно много сказать о количестве различных газов, например озона, и их распределению по высоте. 
  • MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) — фурье-спектрометр для среднего инфракрасного диапазона; этот диапазон важен для слежения за газами, играющими большую роль в климате Земли. 
  • SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) — спектрометр, который сравнивает свет, идущий от Солнца, со светом, отражаемым Землёй; это позволяет получить информацию об атмосфере, через которую проходит отражённый свет.

32015-09-22. Канада рассматривает варианты помощи европейскому космическому агентству по сведению с орбиты космического аппарата Envisat .
Канада может сыграть заметную роль в сведении с орбиты космического европейского космического аппарата Envisat. При этом, согласно предложению канадского комического агентства, работы по уводу спутника с орбиты возможно будет выполнить при помощи разработанных в стране технологий изготовления роботизированных манипуляторов. Возможный срок создания космического аппарата с манипулятором составляет 2021 год. Головным исполнителем работ по систему должна будет выступать MDA. В агентстве также отметили, что существующая орбита аппарата подразумевает, что он будет находиться на ней около 150 лет, а с учетом его габаритов в случае разрушения он может создать большое число обломков. К особенностям предложенной миссии также возможно отнести и то, что аппарат вращается вокруг свой оси, а, следовательно, его захват манипулятором является достаточно сложной задачей.Тэги: Envisat 1Космическое агентство Канады
