SES-7 (also formerly known as ProtoStar-2 / Indostar-2) is a commercial communications satellite operated by SES World Skies (now SES).

Spacecraft

ProtoStar-2 is a geosynchronous communications satellite built by Boeing. It is a BSS-601HP satellite bus. On 15 November 2002, PanAmSat terminated its contract with Boeing Satellite Systems (BSS) for the almost-completed Galaxy-8iR satellite, claiming that Boeing had defaulted on the terms of the contract, and requested US$72 million from Boeing to refund prior advance payments and other costs. The satellite was later converted into the ProtoStar-2 satellite, which was launched in May 2009. Late 2009, it is purchased through auction by SES for SES World Skies unit for US$180 million. The satellite was renamed SES-7 in May 2010.

Launch

Launched on 16 May 2009 at 00:57:38 UTC, since Baikonur Cosmodrome, Site 200/39 for ProtoStar Ltd by Proton-M / Briz-M launch vehicle. Launch arranged by International Launch Services (ILS).

Market

It is positioned at 108.2° East longitude and serves customers in Indonesia, India, Taiwan, the Philippines, and Southeast Asia. Protostar 2 carries 10 (+3) S-band and 22 (+5) Ku-band transponders for optimized HD satellite television direct-to-home (DTH) satellite television service and broadband Internet access across the Asia-Pacific region.{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2009-027A|title="Display: ProtoStar 2 2009-027A|publisher=NASA|date=5 April 2021|access-date=12 April 2021}} {{PD-notice}} The S-band payload is operated under the name of IndoStar-2 (Cakrawarta-2).{{cite web |url=http://space.skyrocket.de/doc_sdat/indostar-2_protostar-2.htm|title=Indostar 2 / ProtoStar 2 → SES 7|publisher=Gunter's Space Page|date=11 December 2017|access-date=12 April 2021}}
