The Government Reference Architecture (GRA) is a reference architecture for modularized communications terminals. To date, the definitions in this reference architecture have centered upon the control plane and the data plane for software defined radios. This paper details the ongoing effort to mature the reference architecture components needed fo...
The Government Reference Architecture (GRA) is a reference architecture for modularized communications terminals. To date, the definitions in this reference architecture have centered upon the control plane and the data plane for software defined radios. This paper details the reference architecture components needed to extend the architecture to s...
The Government Reference Architecture (GRA) is a reference architecture for modularized communications terminals. To date, the definitions in this reference architecture have centered upon the control plane and just a simplistic view of the data plane. This paper details the reference architecture components needed to create an elaborate data plane...
Tightly coupled, poorly encapsulated, hardware and software implementations have resulted in systems that are rigid and fragile. These systems lack desirable architectural attributes including efficient extensibility, technology insertion, hardware and software portability, and effective use of Commercial Off The Shelf (COTS) equipment. The realiza...
The purpose of the Government Reference Architecture (GRA) was to define a modular, open systems architecture that fostered reuse and technology insertion refresh with modular components and product line variants. A graphical model-driven development (MDD) approach was chosen to support rapid design and development of work products that could be qu...
The Government Reference Architecture (GRA) was initiated in response to unique requirements of above 2 GHz Satellite Communications (SATCOM) systems not effectively addressed by the Software Communications Architecture (SCA). Fundamental objectives of the GRA effort were to, 1) develop a modular open systems architecture (MOSA) approach that promo...
The High Bandwidth High Throughput (HBHT) terminal Government Reference Architecture (GRA) is being defined to support cost effective implementation of a network centric, reconfigurable, multi-band family of SATCOM platforms. The architecture is specified as a set of independent modules with well defined interfaces. The primary goal of the GRA is t...
This purpose of this paper is to document an architectural validation approach for the Government Reference Architecture (GRA) for SATCOM terminals. The approach integrates the Virginia Tech OSSIE SCA Core Framework with a UML model of the GRA, coupled with low-fidelity models of the SATCOM components. This approach uses the Rhapsody tool to implem...
This paper describes the high bandwidth high throughput (HBHT) government reference architecture (GRA) effort and utilization of dependency structure matrix (DSM) tools to validate the architecture. This paper is intended to show how the development of GRA compliant modules advances both new and time-tested technologies through establishing a stand...
The U.S. Army has developed a modular architecture for the high bandwidth military tactical satellite communications terminal domain with flexible multiband and multimode capabilities. The architecture was validated and verified using modeling and simulation. The artifacts generated by the model can be used to develop the DoDAF views to obtain cert...
This paper describes a preliminary proof of concept of the Government reference architecture (GRA) that integrates a commercial-off-the-shelf (COTS) universal software radio peripheral (USRP) platform developed for the GNU Radio project, GNU Radio source code for the USRP, and the Virginia Tech based open source software communications architecture...
The move to adopt the modular, open-systems approach to SATCOM development has led to open-standards interfaces both for hardware buses and software infrastructure. A software development methodology is presented that enhances the standard Unified Modeling Language (UML)-based object-oriented modeling and design for SATCOM Terminal development. The...
This paper describes some approaches for implementation of the HBHT GRA in an open source environment. It describes the process associated with engaging industry in developing the GRA Functional Decomposition, validating the GRA through a prototype, creating the GRA as an open standard for the Army HC3 Program and managing to that architecture and...
The HC3 Government Reference Architecture (GRA) is being defined to support cost effective implementation of a network centric, reconfigurable, multi-band family of SATCOM platforms. A session in MILCOM 2007 ldquoHigh Capacity Communications Capability Terminal (HC3)rdquo was devoted to discussions on this topic. Primary GRA architecture goals are...
