[4][5] It is capable of carrying up to 350 kg (770 lb) of payload with a maximum power consumption of 3.4 kW at the end of life.

It uses an integrated chemical propulsion system supplied by EADS Astrium for both orbit raising and station keeping.

[8] It will keep the launch mass of 3 t (6,600 lb), but have enhanced capabilities, being able to carry a 350 kg (770 lb) of payload with a maximum power consumption of 7 kW at the end of its design life.

It will keep the payload and power envelope of the ARSAT-3H while applying the improvements to cost and weight reduction.
