任务简介

SXM-11 是 SiriusXM 公司订购的第 12 颗高功率数字音频广播卫星，由 Lanteris Space（前身为 Maxar、Space System/Loral）建造。该卫星将基于成熟的 IM-1300（前身为 LS-1300）平台，在位于加利福尼亚州帕洛阿尔托的制造工厂建造。SXM-11 配备了一个直径近 10 米的大型网状可展开反射器，使 SiriusXM 节目能够覆盖其收音机（包括移动车辆中的收音机）。

SXM-11 is the 12th high-powered, digital, audio radio satellite built by Lanteris Space (ex-Maxar, Space System/Loral) for SiriusXM. The SXM-11 satellite will be based on the proven IM-1300 (ex-LS-1300)-class platform and built at the company’s manufacturing facility in Palo Alto, California. SXM-11 has a large, mesh, unfurlable reflector almost 10 meters in diameter that allows SiriusXM programming to reach its radios, including those in moving vehicles.
