SHF DAMA Network

Our clean-sheet-of-paper architectural concept is different from any used by the Navy at either UHF or EHF. It takes advantage of the unique attributes of DSCS space and ground segments, compared to other MilBatcom systems. Still, our innovative networking concept is compatible with current and Planned small shipboard SHF terminals. It focuses on the SHF modems and network controllers. It builds on emerging Navy VME standard architectures and uses IF outputs suitable for AN/WSC-6 SHF terminals. The Proposed Phase I work includes analysis and simulation to quantify system Performance under a variety of satellite configuration, terminal, operational, and traffic models. A successful Phase I feasibility Program leads directly to an SHF on-the-air Phase II Proof-of-concept demonstration, including measurements to verify Performance Predicted in Phase I. The high pay-off Phase II program is tailored for a Phase III opportunity to feed the Powerful networking equipment into mainstream SHF terminal Procurements. Our concept builds on ViaSat\'s expertise in key technologies related to SHF networking, including: anti-jam, low Probability of exploitation signaling and coding, satcom modems, embedded-multi^user Time-of-Day encryption, and Demand Assigned Multiple Access network management. The major benefit of the proposed work is to offer the Navy a near-term affordable
