A United Launch Alliance (ULA) Atlas V 531 rocket will launch the SES-20 and SES-21 satellites into near-geosynchronous orbit to provide television broadcasting services across the United States. The commercial dual-payload launch is in service to satellite operator SES of Luxembourg. Liftoff will o...
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.
