The guaranteed availability for the whole ship of 128 500 kBit/s Upload / 448 1000 kBit/s Download and 768 2000 kBit/s Upload / 2048 4000 kBit/s Download at the best are valid within the 10° elevation contour and the 44 dBW EIRP contour of the European coverage zone. The bandwidth may reach 1 Mbit/s under very favourable conditions. Operation is possible up to 0° elevation.
