PHOENIX, Ariz. Honeywell and Inmarsat announced an agreement to develop and deliver commercial satellite communications (COMSATCOM) solutions to the U.S. government. The solutions will be focused on fixed-wing and non-fixed wing aeronautical platforms operating worldwide, including in Arctic regions. 

Through the new strategic alliance, Inmarsat and Honeywell will aim to offer U.S. government users access to a suite of products and services across Inmarsat’s worldwide networks operating in L-band, as well as in the commercial and military Ka-bands.

According to officials, L-band frequencies are lower radio frequencies between the one and two GHz range employed for a variety of applications to include resilient mobility satellite communications. Ka-band radio frequencies in the 26 to 40GHz range offer higher throughput for satellite communications and other applications.   

Inmarsat’s Global Xpress (GX) is a globally available mobile commercial wideband service. In U.S. government operation since July 2014, Inmarsat claims that GX has provided wideband communications across land, sea, and air for assured mobile connectivity and interoperability with government satellite communication systems.
