It has 28 channels, 20 of which provide coverage of Europe, North Africa, the Middle East and central Asia via a fixed widebeam, with the remaining eight connected to a steerable spotbeam, to address new markets in geographical areas outside the widebeam coverage area (notably southern Africa). Services can be simultaneously provided within both coverages.
