尼星1R采用了中国航天科技集团公司所属中国空间技术研究院研制的东方红四号卫星平台,星上装有28路转发器,其中4路C波段,14路Ku波段,8路Ka波段,2路L波段,卫星起飞质量为5100公斤,服务寿命15年,将定点于东经42.5度赤道上空。

卫星覆盖非洲中西部及南部地区、欧洲中东部地区和中亚部分地区,主要用于通信、广播、远程教育、宽带多媒体、导航服务等,将改善国家基础设施,造福边远地区民众,提高人民生活质量。

为了进一步拓展尼星1R的运营前景,尼星1R较尼星一号增加了Ku波段喀什波束,具备了同时为中国和非洲大陆提供商用通信服务的能力;同时,也为中国航天在国际卫星运营市场的拓展奠定了基础。

NigComSat-1R is built on DFH-4 satellite bus developed by CAST, a subsidiary of China Aerospace Science and Technology Corporation (CASC), with 28 transponders on board, including 4 C-band, 14 Ku-band, 8 Ka-band, 2 L-band. The satellite will be launched and positioned at 42.5°East Longitude with a lift-off mass of 5100 kg and a service lifespan of 15-years.

The satellite, covering Central Western and Southern Africa, Central and Eastern Europe, and some Central Asia area, will be mainly applied to communications, broadcasting, Tele-education, broad band multimedia service, navigation service and so on, which will improve the national infrastructure and benefit the people in rural areas.

To further extend the operation and marketing of NigComSat-1R, Ku Kashi Beam was added to NigComSat-1R. The Satellite will supply the communications between Nigeria and China. Moreover, the utilization of satellite capacity will be enhanced without any extra cost.
