Mission

SES-20 & SES-21 are a pair of C-band communication satellites built by Boeing, using the highly efficient all-electric propulsion BSS-702SP satellite bus. These satellites will enable SES to clear 280MHz of mid-band spectrum for 5G use while seamlessly migrating SES’s existing C-band customers and ensuring the continued delivery of digital television to nearly 120 million American TV homes and other critical data services.
