U.S. Army Future Combat System (FCS) Simulation and TrainingEnvironmental Representation Requirements and the Interchange ofEnvironmental Data

摘要

The Future Combat System (FCS) Training and IS&T (Integrated Simulation and Test) Integrated Product Teams (IPT) have a requirement to support all facets of embedded training across the entire FCS. This requirement is levied through a Key Performance Parameter (KPP) called Embedded Training. The Training Common Component (TCC) program was established with Environmental Representation (ER) as a key TCC. The objective of the ER TCC is to provide a consistent and authoritative representation of operationally relevant environmental features and attributes to support embedded training throughout the FCS.rnTo accomplish the required embedded training, a three step process was identified for the ER TCC. The first step was to identify applicable ER concepts needed to support embedded training applications. Once identified, these concepts were unambiguously defined using an International Standard dictionary of concepts; the SEDRIS Environmental Data Coding Specification (EDCS). These two parts established the embedded training environmental representation requirements.rnThe second step was to develop the Logical Data Model (LDM) to represent the requirements identified in step one. This step was also accomplished in a two part harmony. The first was to identify a method that would provide the structure for the LDM. In most cases of LDM development the structure and concepts are intertwined. If concepts are changed, added, or deleted, then the LDM potentially has major revisions. However, by establishing the structure first and then adding the concepts in a second part, the addition of new concepts will not cause major revisions to the LDM. Once again, an International Standard, the SEDRIS Data Representation Model (DRM), was used to provide the structure and the concepts were added to provide the details for the LDM. The third step is transmitting the data found in the data model to user applications. This was accomplished using the International Standard SEDRIS Transmittal Format (STF) and applicable converters are used to supply point applications with all the necessary data in their user defined runtime format. The OneSAF constructive simulation is a target application used to show how the data can be prepared and remain portable. All three steps are required for portability of data and interoperability. Thus, this paper shows a complete process for data portability and how environmental data can be defined, prepared, and transmitted to enhance interoperability using a well defined process based in international standards.
