Modern Approach to Integrated Architecture Technology

Tau Technologies will deliver to the Space Development Agency Integrated Architecture Technology Testbed (IATT), whose benefit will be the ability to confidently and accurately result in the generation of, for each National Defense Space Architecture (NDSA) element, cost, schedule and performance acquisition requirements.  This capability to enable SDA to confidently perform comparative analysis, trade space development, and scenario scoring (link budgets, coverage, constellation design, network routing, optimization, etc.). Tau’s proposes NEXt generation Unified Simulation Suite (NEXUSS) representing an end-to-end Modeling Simulation and Analysis (MS&A) Integrated Architecture Technology Testbed (IATT). NEXUSS is a simulation concept that connects diverse Commercial Off the Shelf (COTS) and Government Off the Shelf (GOTS) simulation tools to provide a flexible and extensible state-of-the-art architecture modeling capability enabling rapid evaluations of SDA Architectures. NEXUSS provides a Model-Based System Engineering (MBSE) simulation leveraging industry standards like System Modeling Language (SysML) and Cameo Systems Modeling tools.  GOTS and COTS tools form the backbone of NEXUSS. Tau leverages past GOTS Advanced Framework for Simulation Integration and Modeling (AFSIM) development maps to model the NDSA layers. An IATT prototype has been tried out in two analyses: a comparative analysis and a scenario scoring analysis. The comparative analysis explored how well constellations with varying parameters viewed specific combinations of ground stations. A 9-task schedule is proposed, which incrementally builds up over two years a software suite that will provide (a) manual or automatic optimization, (b) on standalone or distributed environments, (c) of Performance, Cost, and Schedule metrics at (d) the UNCLASS and TS/SCI levels for (e) all 7 NDSA layers.
