Intelsat IS-27 replacing Intelsat 805
Intelsat S.A. has commenced construction of the Intelsat 27 satellite (IS-27). IS-27 will have a hybrid C- and Ku-band design for media and network customers and will be augmented with a 20 x 25 kHz channel UHF payload for use in government applications. IS-27 is expected to be launched by December 2012 and will be placed in the Atlantic Ocean Region as a replacement for the Intelsat 805 satellite. The IS-27 UHF hosted payload provides capability to complement the existing UHF Follow-On (UFO) and future Multi-User Objective System (MUOS) satellites. The payload supports DAMA and IW operations, and is digitally tunable and completely interoperable with existing terminals.
In March 2010, the Navy submitted a UHF augmentation plan to Congress. A commercially hosted UHF payload was one of the solutions described to mitigate the shortfall in UHF capability. On May 10, 2010, SPAWAR issued a Sources Sought notice to industry requesting solutions for UHF augmentation. “Our intended customers for this payload are the Navy and DoD tactical users, as well as NATO and other allies,” said Kay Sears, President of Intelsat General Corporation. “The requirements outlined in the Sources Sought were at the forefront of our payload design process. Intelsat’s payload will arrive at a critical time and location to sustain warfighter communications.” Sears continued, “We understand the military’s need for control and autonomy, and plan to offer our customers a variety of different contractual options for this UHF payload.” Intelsat signed an agreement with Boeing Space and Intelligence Systems for manufacturing of IS-27 earlier this month. Intelsat authorized Boeing to proceed with the UHF hosted payload in the second quarter of 2010 for long-lead construction in order to meet a launch date in 2012.
