任务简介
SXM-8 是一颗用于 SiriusXM 数字音频广播服务（DARS）的大型高功率广播卫星。 2016 年 7 月，Space Systems/Loral（SS/L）获得合同，基于其 SSL-1300 平台建造两颗卫星——SXM-7 和 SXM-8。卫星设计工作在 S 波段。每颗卫星将产生超过 20 千瓦的功率，并配备大型可展开天线反射器，从而无需地面大型碟形天线即可向收音机广播。 SXM-8 旨在替代 XM-4 卫星。SXM-7 原计划替代 XM-3，但在发射后 6 周于轨道上发生故障。
原文
SXM-8 is a large high power broadcasting satellite for SiriusXM's digital audio radio service (DARS). Space Systems/Loral (SS/L) got in July 2016 the contract to build the two satellites based on their SSL-1300 bus - SXM-7 and SXM-8. Satellite design operates in the S-band spectrum. Each satellite will generate more than 20-kW of power and will have a large unfurlable antenna reflector, which enables broadcast to radios without the need for large dish-type antennas on the ground. SXM-8 is meant to replace the XM-4 satellite. SXM-7 was meant to replace the XM-3, but suffered a failure in orbit 6 weeks after its launch.
