C4I SATCOM Networking

High-Speed Modems for Air, Land, and Sea

As commanders and warfighters need to share and disseminate information to military forces everywhere, Viasat’s SATCOM modems and C4I networking platforms serve as a high-speed, high-capacity tactical networking backbone to reach every corner of the battlespace. Viasat powers C4I networks like US Army WIN-T, US Air Force GBS, DISA Teleports, NATO SGS, and many more with a wide range of networking topologies and SATCOM technologies. With DoD MIL-STD and NATO designations, Viasat’s modems are the military and de facto standards for superior bandwidth efficiency, capacity, security, and performance to ensure at-the-halt and on-the-move communications and fast, reliable access to information across all domains.
