The Integrated Data Assimilation Architecture (IDAA) addresses the fundamental problem of command, control, and communications systems interoperability. Interoperability of Explorations systems is necessary to improve reliability, reduce complexity, increase software and hardware reusability, and enable multi-developer / multi-agency support. The IDAA architecture consists of a software component, the BioNet middleware, and a hardware component, a Mobile Data Acquisition and Communications processing System (MDACS). Development and advancement of the BioNet middleware was the primary focus of the Phase I STTR effort. Continued BioNet middleware development will occur as a proposed Phase II activity along with the development of the MDACS generic hardware platform. From a functional perspective, the BioNet middleware provides a standards-based command and control capability, while the MDACS provides a generic space-rated hardware platform for general-purpose computations and communications.
