亚太7号卫星由法国泰雷兹阿莱尼亚宇航公司为香港亚太通信卫星有限公司研制，卫星采用Spacebus 4000 C2卫星平台，发射质量为5,054千克，设计寿命逾15年。亚太7号卫星共有56路转发器 (28路C波段和28路Ku波段) ，发射后将定点于东经76.5度赤道上空以接替在该轨位运行的亚太2R卫星。亚太7号卫星的C波段转发器可为亚洲、非洲、澳大利亚、欧洲等地提供电视传输和卫星通信服务，Ku设计有多个波束，包括中国、中东北非、非洲以及一个移动波束，为覆盖区域提供波束内以及跨波束的广播和通信服务。

香港亚太通信卫星有限公司是亚太地区主要的卫星运营商之一，其在轨的“亚太卫星”可覆盖亚洲、欧洲、非洲和澳大利亚等全球约75%人口的地区，为这些地区的广播和通信客户提供优质的卫星转发器、卫星通信以及广播电视传输等一站式服务。

泰雷兹阿莱尼亚宇航公司是世界主要卫星制造商之一，亚太7号卫星是长征系列运载火箭发射的第七颗该公司研制的卫星。

APSTAR-7 satellite is an advanced telecommunications
satellite based on Spacebus 4000 C2 of Thales Alenia Space France (TASF) with a lift-off mass of 5,054 kg and a design lifetime over 15 years. The satellite has 56 operational transponders (28 C-band and 28 Ku-band) onboard, and will replace the current APSTAR-2R satellite at 76.5°East Longitude. APSTAR-7 satellite's C-band global beam covers Asia, Africa, Australia and part of Europe and its multiple Kuband beams, including China Beam, Middle East & North Africa Beam, Africa Beam and a Steerable Spot Beam, are able to provide in-beam and cross-beam broadcast and telecommunication services.

APT Satellite Company Limited is one of the leading satellite operators in the Asia Pacific region. Its fleet of five APSTAR satellites provides quality and “one-stop-shop” broadcast and telecommunications services covering about 75% of the world's population in Asia, Europe, Africa and Australia.

Thales Alenia Space France (TASF) is one of the leading satellite manufacturers in the world. APSTAR-7 is the 7^th TASF-manufactured satellite launched by Long March launch vehicle.
