EchoStar 105/SES-11 Mission Mission Overview SpaceX’s Falcon 9 rocket will deliver EchoStar 105/SES-11, a commercial communications satellite, to a Geostationary Transfer Orbit (GTO). SpaceX is targeting launch of EchoStar 105/SES-11 from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center, Florida. The two-hour launch window opens on Wednesday, October 11 at 6:53 p.m. EDT, or 22:53 UTC. A two-hour backup launch window opens on Thursday, October 12 at 6:53 p.m. EDT, or 22:53 UTC. The satellite will be deployed approximately 36 minutes after liftoff. Falcon 9’s first stage for the EchoStar 105/SES-11 mission previously supported SpaceX’s 10th resupply mission to the International Space Station (CRS-10) in February of this year. Following stage separation, Falcon 9’s first stage will attempt a landing on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.
EchoStar 105/SES-11, a high-powered hybrid Ku and C-band communications satellite, is a dual-mission satellite for US-based operator EchoStar and Luxembourg-based operator SES. EchoStar 105/SES-11 provides EchoStar with 24 Ku-band transponders of 36 MHz, marketed as EchoStar 105, while it provides SES with a C-band payload of 24 transponders, marketed under the name SES-11. EchoStar 105/SES-11 replaces Ku-band capacity for AMC-15 and C-band capacity for AMC-18 at SES’ well-established 105 degrees West orbital slot. EchoStar 105 was tailored to meet the Ku-band capacity needs of EchoStar’s enterprise, media and broadcast, and U.S. government service provider customers, offering coverage of the 50 U.S. states and expanded reach to the Gulf of Mexico and the Caribbean. SES-11, designed to accelerate the development of SES’s U.S. prime video neighborhood and the delivery of High definition (HD) and ultra-high definition (UHD) channels, joins SES-1 and SES-3 at the center of SES’s robust North American orbital arc, which reaches more than a hundred million TV homes. It also replaces C-band capacity for AMC-18, which SES offers over North America, including Hawaii, Mexico and the Caribbean, empowering businesses and governments to capture new opportunities and expand their reach.
