ULA will launch the 10th Wideband Global SATCOM (WGS-10) on a Delta IV Medium (5,4) on Friday, March 15, 2019. The launch is scheduled for 6:56 p.m. EDT from Space Launch Complex-37 at Cape Canaveral Air Force Station from Florida’s Space Coast.
WGS-10 is the fourth Block II follow-on satellite and supports communications links in the X-band and Ka-band spectra. While Block I and II satellites can instantaneously filter and downlink up to 4.410 GHz, WGS-10 can filter and downlink up to 8.088 GHz of bandwidth. Depending on the mix of ground terminals, data rates and modulation and coding schemed employed, a single WGS satellite can support data transmission rates over 6 Gbps, and WGS-10 with its advanced digital channelized may support over 11 Gbps.
WGS-10 will be with eight flight of the Delta IV Medium+ (5,4) configuration. All launches in this configuration have delivered WGS missions to orbit. This mission will also be the 39th launch of the Delta IV since its inaugural launch in 2002.
