Abstract
Current communications relay satellite systems do not meet validated needs for global ocean observing system data collections. A complete system architecture, including the network for providing access between the data providers and users, and the system for managing the data generated in both real-time and delayed-mode, has yet to be developed. Global ocean observing system data collections require a low-cost, robust solution using bi-directional delay-tolerant messaging capable of providing internet-like services. The work proposed for Phase II will further develop the technologies demonstrated in Phase I to enable a robust, cost-effective two-way (space-to-ground and ground-to-space) communication relay system with significant increases in collected data from autonomous platforms. Primary is a two-way delay-tolerant messaging capability providing internet-like services on a global basis. Enablers include increased signal-to-noise at the microsatellite via coding and a store-and-forward overlay network used in a manner similar to e-mail. The proposed microsatellite architecture will allow evolution and expansion for future sensors, and it decouples autonomous platforms from future space segment system upgrades. The system could be deployed as a mix of stand-alone microsatellites and secondary payloads aboard host space vehicles.
