Boeing is building four 702HP spacecraft to provide new Ka-band global and high-capacity satellite services to Inmarsat, the leading provider of global mobile satellite communications services. Leveraging Boeing's extensive expertise in Ka-band satellite communications systems, the new satellites will join Inmarsat's fleet of geostationary satellites that provide a wide range of voice and data services through an established global network of distributors and service providers. The Boeing satellites will provide Inmarsat with the ability to adapt to shifting subscriber usage patterns of high data rates, specialized applications and evolving demographics over a projected 15-year lifetime. The first Inmarsat-5 satellite was launched on December 8, 2013. In a separate arrangement, Boeing has also entered into a distribution partnership with Inmarsat to provide L- and Ka-band capacity services to government and commercial users.
