UHF SATCOM Terminals

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 stand-alone 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 available worldwide. Under contract with DISA, Viasat has successfully installed and tested IW UHF network control stations around the world.

UHF SATCOM Terminals

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

UHF Network Management Solution 

Viasat's Visual Integrated SATCOM Information, Operation and Networking (VISION) is an integrated user-friendly interface to manage all 25-kHz legacy DAMA and IW networks and services, and the latest addition to our UHF portfolio. Leveraging MIL-STD TDMA protocols, the Viasat UHF DAMA/IW Network Management Solution (NMS) allows for simultaneous communications of UHF SATCOM terminals and networks.

Viasat's VISION maximizes channel efficiency and provides users with reliable voice and data connections, supporting better voice quality and higher data throughput. Viasat's VISION is a customized system based on user requirements, allowing for increased connectivity to UHF SATCOM terminals on land, sea, and, in the air. 

DAMA Orderwire Channel Controller Trainer/Simulator (DOCCT/S)

Develop, integrate, and train on UHF satellite communication equipment without the expense and time constraints associated with accessing live satellite channels.

DOCCT/S has the flexibility to address an entire range of UHF DAMA satellite communications equipment training, integration, and mission rehearsal requirements.
