ARSAT-3K is a geostationary communications satellite bus designed and manufactured by INVAP of Argentina for the local telecommunication company ARSAT S.A. [ 2] [ 3] kW of power generation and 3,000 kg (6,600 lb) of launch mass) three axis stabilized platform designed, manufactured and tested completely in Argentina.[ 4] [ 5] [when? uses only chemical propulsion , but a hybrid solution which would use bi-propellant propulsion for orbit raising and electric propulsion for station keeping is being developed. A purely electric propulsion version is planned.[ 6]
ARSAT-3K
The ARSAT-3K is the initial version of this bus. It is comparable to the Thales Alenia Space Spacebus 3000B2 . It uses an integrated chemical propulsion system supplied by EADS Astrium for both orbit raising and station keeping .[ 7]
ARSAT-3H
The ARSAT-3H is the second version of this bus, which initiated its development during 2015. It will use an hybrid approach with bi-propellant propulsion for orbit raising and electric propulsion for 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.[ 8]
ARSAT-3E
The ARSAT-3E will be the third version of the platform. It will use electric propulsion exclusively. It will keep the payload and power envelope of the ARSAT-3H while applying the improvements to cost and weight reduction.[ 8]
