Спутник ДЗЗ. DMC Consortium. [Редактировать]

Консорциум DMC - международная программа между, Нигерией, Соединенным Королевством, Турцией,  Алжиром, Китаем, Вьетнамом и Таиландом. Каждый из партнеров по DMC должен предоставить по космическому аппарату практически идентичной конфигурации. Группировка КА предназначенны для оказания услуг по предоствращению черезвычайных ситуаций с оперативным предоставлением данных. 
Аппарты в группировке:

  • Alsat 1 - принадлежащий Алжиру 
  • NigeriaSat-1 - принадлежащий Нигерии 
  • U.K-DMC - принадлежащий Соединенному Королевству 
  • Bilsat-1 - принадлежащий Турции 

Сотрудничество Нигерии в DMC позволило ей приобрести передовые микроспутниковые технологии, а именно: 

  • недорогостоящие микроспутниковые технологии на НОО 
  • технологии построения и управления орбитальными группировками
  • динамические спутниковые технологии дистанционного зондирования Земли

С помощью данной группировки Нигерия будет способна иметь национальную независимое, доступное, недорогое, гибкое и динамическое дистанционное зондирование Земли. Также планируется внедрить результаты ДЗЗ в различные социально-экономические области, в частности: 

  • cельское хозяйство,
  • экологический контроль,
  • управление водными ресурсами,
  • контроль над нефтепроводами. 

Пространственные и многоспектральные возможности группировки похожи на те, что предоставляет система Landsat. Однако, будет обеспеченно более короткое время перепосещения.

The main difference between MSS and a cell system is—mobility! MSS has proven its efficacy for providing communication services across the globe, especially in servicing those areas that have poor or few communication options, including developing countries and the vast oceans of Earth. With MSS, there are several positive aspects. Some include: • very high bit rates • channels dynamically assigned to users who are located in various areas of the world • the cost of doing business (i.e., the transmission itself) is independent of distance • a station that’s handling the data transmission can, itself, receive its own transmission, which is a definite plus when transmission control is needed There are other considerations as well as various plusses and minuses for MSS providers when using either a geosynchronous or low Earth orbit satellite. To obtain a clearer view of the MSS market, I asked one of the leading MSS providers to comment on this segment of the satcom industry. Iridium Satellite’s Don Thoma, the company’s Executive Vice President, took up the cause. He noted the MSS market growing this year and added in those areas where he believes the growth will be experienced. “Iridium Satellite continues to achieve double-digit growth across all vertical markets for ...
