Спутник ДЗЗ. Megha-Tropiques. [Редактировать]

Megha-Tropiques – фрацузско-индийский спутник, предназначенный для исследования круговорота воды в природе и влиянии этого процесса на изменение климата в тропических областях планеты. Название спутника составлено из двух слов: Megha на санскрите означает "облако", а Tropiques - "тропики" по- французски. На спутнике установлено 3 основных прибора:

  • многочастотный микроволновый сканирующий радиометр MADRAS (Multifrequency Microwave Scanning Radiometer), который будет поставлять информацию о дождях над поверхностью океанов, о содержании водяного пара в атмосфере, о количестве жидкой воды в облаках и о конвективных дождях над сушей и морем;
  • многоканальный микроволновый радар SAPHIR, с некогерентным накоплением сигнала, позволяющий получать вертикальные профили температуры и влажности в атмосфере по отраженным от пограничных слоев эхо-сигналам;
  • многоканальный прибор SCARAB, с помощью которого будет измеряться освещенность поверхности земли.

Прибор MADRAS Индия и Франция разработали совместно, а SAPHIR и SCARAB поставлены Французским космическим агентством. Сам спутник Megha Tropiques построен на базе платформы PROTEUS, также французского производства. Спутник Megha Tropiques выводится на орбиту высотой 867 км и наклонением 20 градусов. Обслуживать его на орбите будет Французское космическое агентство, а научные данные будут обрабатываться в Бангалоре (Индия).
