ARSAT-3K [SEP] manufacturer
ARSAT-3K
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 of launch mass) three axis stabilized platform designed, manufactured and tested completely in Argentina. It is capable of carrying up to of payload with a maximum power consumption of 3.4 kW at the end of life. It currently uses only chemical propulsion, but an 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.
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.
Platform Versions 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
