ARSAT-2 is a geostationary communications satellite operated by ARSAT and built by the Argentine company INVAP. [6] It was launched from French Guiana alongside Sky Muster satellite using an Ariane 5ECA rocket on September 30, 2015 at 20:30hs UTC, becoming the 400th satellite to be launched by Arianespace. [7] [8] It is licensed to be located at 81° West longitude geostationary slot. [9] [10] ARSAT-2 is the second geostationary satellite built in Argentina, after ARSAT-1. Structurally and mechanically it is a copy of the ARSAT-1, the only difference being the payload and thus it has different antenna configuration. [11] [2]

Payload

ARSAT-2 payload was supplied by Thales Alenia Space. [12] It consists of both Ku band and C band sections. [2]

The Ku band has 20 physical transponders. Of those, sixteen have a 36 MHz bandwidth and four have 72 MHz. Thus the satellite has a maximum capacity of 864 MHz Ku or 24 transponder equivalent. A 2 m (6.6 ft) deployable antenna and a 1.3 m (4.3 ft) fixed Gregorian antenna. [2]

The C band section has a single 1.6 m (5.2 ft) deployable antenna that is fed by six physical transponders. Four have 72 MHz of bandwidth and the other two have 88 MHz. The total available C Band bandwidth is thus 464 MHz (or 12.9 transponder equivalent). [2]

It was operated by Nahuelsat S.A., the first satellite operator of Argentina from its ground station in Benavidez, province of Buenos Aires. It was transferred in 2006 ARSAT S.A., along all other Nahuelsat S.A. assets. Satellite mass was 1,790 kg (3,950 lb) wet, 828 kg (1,825 lb) dry with a nominal lifetime of 12.33 years. It had eighteen 54 MHz transponders implemented with 55W TWTAs in three Ku band and extended Ku band coverages. Thus, it had 27 transponder equivalent or 972 MHz of Ku Band bandwidth.

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 three axis stabilized platform designed, manufactured and tested completely in Argentina. 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 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.

The Sky Muster satellites are two geostationary (GEO) communications satellites operated by NBN Co Limited and built by SSL.
