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