Mission

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.
