UHF Satcom Products

UHF for Ship and Shore

ViaSat is the world leader in shipboard and fixed station UHF satellite communications for defense organizations. From single user terminals to complete standalone UHF systems for sovereign controlled satellite channels, we provide terminals, modems, simulators, network management, and RF infrastructure. Our terminals are Joint Interoperability Test Command (JITC) and NSA certified to ensure compliance with Legacy Demand Assigned Multiple Access (DAMA) MIL-STDs and provide interoperability with fielded UHF satcom terminals.

Channel Optimization with Integrated Waveform

UHF MILSATCOM has a long history enabling beyond line-of-sight communication across the battlespace and it continues to provide assured access under disadvantaged weather conditions and coverage. Doubling current UHF capacity and enabling cell phone-like calling with less latency and better voice quality, the next generation Integrated Waveform (IW) is now available worldwide. Under contract with DISA, ViaSat has successfully installed and tested IW UHF network control stations around the world.

UHF Satcom Terminals

ViaSat RT-18XX UHF satcom terminals use the same modules (cards), so you keep spares to the minimum.
