Fast, reliable, at-the-halt and on-the-move communications

Viasat powers C4I networks like U.S. 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 has a history of providing satellite modems that are the military and de facto standards for superior bandwidth efficiency, capacity, security, and performance.

Modem, waveforms, and satellite network systems

Viasat SATCOM modems deliver warfighters fast, secure access to information across all domains, operating over X, C, Ku, Ka satellite bands and the following waveforms: LinkWay, a full-mesh, bandwidth-on-demand MF-TDMA military waveform; EBEM, a point-to-point highly efficient FDMA waveform; and Arclight, a Hub-spoke waveform, especially tailored for air and ground mobile platforms.
