Galaxy 36



Galaxy 35 and 36 will use their own propulsion systems to reach a circular geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator, a process that will take a few weeks using a series of thruster firings to reshape its orbit. The satellites will enter service early next year to provide C-band television broadcast services over the United States, part of a transition mandated by the Federal Communications Commission to free up a slice of the C-band spectrum for terrestrial 5G broadband connectivity.

The transition to 5G requires satellite operators like Intelsat to build and launch new satellites to maintain their C-band programming for cable TV networks in the United States. The new C-band satellites are designed to operate in a more narrow segment of the C-band spectrum, permitting other frequencies to switch over to 5G services.

The Galaxy 35 and 36 satellites are designed for 15-year missions to replace aging members of Intelsat’s fleet launched in 2002 and 2005 and operating at 89 degrees west and 95 degrees west longitude. Galaxy 35 and 36 are the fifth and sixth new C-band satellites Intelsat has launched this year. Four new Intelsat C-band spacecraft launched on a pair of SpaceX Falcon 9 rockets earlier this year, and a seventh and final new C-band payload will launch on a SpaceX mission in 2023.
