Robust Ultra High Frequency (UHF) Satellite Communications Protocol for UUVs

"Wavix proposes to capitalize on its unique combination of expertise in satellite communications and oceanographic systems to develop an optimized-protocol solution to the problem of RF satellite communications in disadvantaged marine environments. Oursolution will invoke a diverse but coordinated array of noise-mitigation techniques that function at the lowest levels of the 7-layer OSI Model, namely, the Physical Layer and the Link Layer of the protocol.In this Phase-I effort we will characterize the physical marine environment for the requirements it places on RF systems. Working from those requirements, we will develop a parameterized conceptual model for low-level protocols that addresses the degradedperformance faced by maritime users. We will also consider compatible error-reduction strategies and approaches to embedding higher-level protocols that can further increase data-transmission efficiency.In modeling the low-level protocol, our requirements analysis will go beyond just noise characteristics. We also will consider constraints imposed by the physical limitations of the application, e.g., small UUVs or profiling buoys of limited power, weight,and size, as well as compatibility with existing UHF SATCOM systems. Wavix has an ongoing business in satellite communications, with our current major customer being users of e-mail services in developing countries. Our intention from the start was, andremains, to serve the oceanograp
