Спутник связи. NigComSat. [Редактировать]

Нигерийский спутник связи оснащённый 4 транспондерами C-диапазона, 14 транспондерами Ku-диапазона, 8 Ka-транспондерами и 2-мя для L-диапазона. В зону покрытия спутника входит Африка и частично Европа. Можно предположить, что на Европу спутник будет "светить" в C-диапазоне, т.к. поблизости к нему на орбите располагются два турецких спутника — "Turksat 1C" и "Turksat 2A", работающие в Ku-диапазоне.
