ARSAT-2 is a geostationary communications satellite operated by ARSAT and built by the Argentine company INVAP.[1] 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.[2][3] It is licensed to be located at 81° West longitude geostationary slot.[4][5] 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.[6][7]

Payload

ARSAT-2 payload was supplied by Thales Alenia Space.[8] It consists of both Ku band and C band sections.[7]

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 Шаблон:Convert deployable antenna and a Шаблон:Convert fixed Gregorian antenna.[7]

The C band section has a single Шаблон:Convert deployable antenna that is fed by six physical transponders. Four have 72Mhz of bandwidth and the other two have 88 MHz. The total available C Band bandwidth is thus 464 MHz (or 12.9 transponder equivalent).[7]
