ARSAT-3K is a geostationary communications satellite bus designed and manufactured by INVAP of Argentina for the local telecommunication company ARSAT S.A. It is a small (4.2 kW of power generation and {{convert|3000|kg|lb|abbr=on}} of launch mass) three axis stabilized platform designed, manufactured and tested completely in Argentina. It is capable of carrying up to {{convert|350|kg|lb|abbr=on}} of payload with a maximum power consumption of 3.4 kW at the end of life. It currently{{when|date=March 2024}} 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.
Platform Versions
=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.
=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.
It will keep the launch mass of {{convert|3|tonne|lb|abbr=on}}, but have enhanced capabilities, being able to carry a {{convert|350|kg|lb|abbr=on}} of payload with a maximum power consumption of 7 kW at the end of its design life.
=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.
List of satellites
The Argentine Geostationary Satellite Plan 2015-2035 (Spanish: {{lang|es|Plan Satelital Geoestacionario Argentino 2015-2035}}) establishes a roadmap for the platform development until 2035.
