亚太6E卫星是中国航天科技集团有限公司（以下简称“航天科技集团”）所属中国长城工业集团有限公司（以下简称“长城公司”）提供的第十三颗通信卫星，依据长城公司与香港亚太星联卫星有限公司（以下简称“星联公司”）签署的亚太6E卫星在轨交付合同执行。

亚太6E卫星由航天科技集团所属中国空间技术研究院（以下简称“五院”）研制，采用东方红三号E（DFH-3E）卫星平台，配置 25 个 Ku 用户波束和 3 个 Ka 信关站波束，通信容量约 30Gbps，拟定点于134°E（与亚太6C/6D卫星共轨运营），设计寿命15年，起飞重量4300kg，其中卫星重量为2090kg，独立推进舱为2210kg。

亚太6E卫星聚焦东南亚市场，为该地区提供高性价比的高通量宽带通信服务

亚太6E卫星不仅是东方红系列新一代经济型全电推商业通信卫星，更是我国首颗全自主实现轨道转移的卫星亚太6E的成功发射无论是对于实现卫星平台高承载、低成本，提升我国卫星平台国际竞争力，还是对于实现卫星全自主轨道提升和长期在轨自主工作，提升我国卫星平台智能自主水平，均具有举足轻重的意义。

长征二号丙运载火箭由航天科技集团所属中国运载火箭技术研究院（以下简称“一院”）研制，作为中国常规液体推进剂火箭的基石，它充分继承了长征系列运载火箭所采用的经飞行验证的成熟技术本发任务采用长二丙两级状态基本型，配合4200C型整流罩，起飞重量达244吨，运载火箭将亚太6E卫星和独立推进舱组合体送至近地点200公里，远地点500公里，倾角28.5°的过渡轨道。

随后由可分离独立推进舱变轨至中间轨道，分离后再由卫星自带霍尔/离子两套电推进系统自主变轨至同步轨道本次发射是长征二号丙运载火箭的第66次发射，也是长征系列运载火箭的第460次发射星联公司是由航天科技集团下属的五院、香港亚太通信卫星有限公司（以下简称“亚太公司”）、长城公司、一院共同出资在香港设立的卫星运营公司。

亚太6E卫星是长城公司首次向星联公司在轨交付通信卫星作为DFH-3E平台的首发星，也是首颗国产全电推进的同步轨道通信卫星，亚太6E卫星将编入亚太公司星队，向东南亚地区提供高通量宽带通信服务（HTS）长城公司是航天科技集团的全资子公司，是中国政府授权的从事商业发射、卫星系统以及从事空间技术合作的商业机构，是中国航天产品及服务的系统集成商，能够为中外客户提供发射服务、卫星在轨交付、卫星地面站建设、卫星应用、项目融资、保险、人员培训及技术转让等整体解决方案，全方位、一站式服务可满足客户多方位需求。

迄今长城公司已为境内外客户实施了13个通信卫星在轨交付项目，向尼日利亚、委内瑞拉、巴基斯坦、玻利维亚、老挝、白俄罗斯、阿尔及利亚等多个国家和地区出口了通信卫星系统LM-2C LAUNCHES SUCCESSFULLY APSTAR-6E COMMUNICATIONS SATELLITE

APSTAR-6E Communications Satellite, the first Chinese all-electric propulsion communications satellite, was launched at 02:10 am on January 13th, 2023 (Beijing time) by the LM-2C launch vehicle from Xichang Satellite Launch Center (XSLC) at Sichuan Province of China. The satellite entered into the predetermined orbit successfully.

APSTAR-6E is the 13th communications satellite conducted by China Great Wall Industry Corporation (CGWIC), a subsidiary of China Aerospace Science & Technology Corporation (CASC). The procurement contract of in-orbit delivery for the APSTAR-6E Communications Satellite was signed and performed by CGWIC and the APSTAR Alliance Satcom Limited (APAS).

The APSTAR-6E satellite is designed and developed by China Academy of Space Technology (CAST), a subsidiary of China Aerospace Science and Technology Corporation (CASC), based on its Dong Fang Hong(DFH)-3E platform. The satellite contains twenty-five (25) Ku-band user beams and three (3) Ka-band gateway beams on board with a 30Gbps payload capacity. The satellite has a designed lifetime of 15 years and will be positioned at 134°E (co-located with APSTAR-6C and APSTAR-6D). The lift-off mass of the satellite/separable propulsion system (SPS) is 4,300kg, for the satellite being 2,090kg and the SPS 2,210kg. Focusing on the customized payload market in South East Asia, the APSTAR-6E satellite will provide cost effective high throughput communication services.

APSTAR-6E satellite is the new generation of all-electric propulsion commercial satellites in DFH series, and also the first Chinese satellite to achieve autonomous orbit transfer. The successful launch of the APSTAR-6E satellite marks a step into a new era of high-capacity and low-cost satellite platforms, and improves competitiveness in the international marker. Meanwhile, the satellite will achieve autonomous orbit raising and autonomous in-orbit operation, enhancing the autonomous capability of DFH satellites.

The LM-2C launch vehicle is developed by China Academy of Launch Vehicle Technology (CALT), a subsidiary of CASC. As the foundation of liquid launch vehicle in China, the LM-2C launch vehicle inherits the mature launch technology verified by Long March series launch vehicles. The LM-2C launch vehicle selected for this mission is a basic two-stage type, with the 4200C fairing and a lift-off mass of 244t. Both the Satellite and the SPS will be injected into a transfer orbit, defined by apogee of 500km, perigee of 200km, and inclination of 28.5°, by the launch vehicle. The satellite will eventually reach the geostationary orbit by its SPS and its electric propulsion system of Hall thrusters and Ion thrusters. This launch mission is the 66th flight of the LM-2C launch vehicle and the 460th flight of the Long March family.

APAS is a satellite operation company based in Hong Kong, co-founded by CAST, the APT Satellite Company Limited (APT), CGWIC and CALT, all subsidiaries of CASC. The APSTAR-6E satellite is the first communication satellite program of APAS. As the first satellite based on the DFH-3E platform, as well as the first Chinese all-electric propulsion GEO communication satellite, the APSTAR-6E satellite will join the APSTAR FLEET. Targeting the Southeast Asia, the APSTAR-6E satellite will offer high throughout (HTS) service to the potential customers.

CGWIC, the whole-owned subsidiary of CASC, is a commercial agency authorized by the Chinese government to operate commercial launches, satellites system and technology cooperation. It is a system integrator for China aerospace products and services. It can offer complete the satellite in-orbit delivery and the construction of satellite ground systems for international and domestic customers, with all-round and one-stop service to meet the diversified demands of the customers. CGWIC has conducted 13 in-orbit delivery communications satellite programs to its international customers by far, and has delivered its communications satellite system to multiple countries and regions including Nigeria, Venezuela, Pakistan, Bolivia, Laos, Belarus and Algeria.
