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] It is a small (4.2 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] 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 currently[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]
