Live Training Transformation (LT2) product line applied standards for reusable integrated and interoperable solutions

The U.S. Army Program Executive Office (PEO) Simulation Training and Instrumentation (STRI) has established a Live Training Transformation (LT2) product line approach to developing a Family of Training Systems (FTS) that provide the ground maneuver training range functions supporting Army live and Joint training environments. The success of the LT2 program strategy is dependent on defining standards and initiatives derived to promote systematic reuse of software and interoperability solutions for the LT2 products. Application of LT2 product line standards have matured reducing life cycle development and sustainment costs through the creation of common reusable architectures providing integrated and interoperable training solutions for the LT2-FTS deployable to Army Ranges. LT2 standard initiatives cover the following primary areas of technology development: Tactical Engagement Simulation System (TESS), training instrumentation systems, software architecture, targetry and battlefield effects, and Joint Live-Virtual-Constructive interoperability. Approved and established standards include Common Training Instrumentation Architecture (CTIA), OneTESS, Family of Army Systems and Integrated Targetry (FASIT), Integrated Player Unit (IPU), Common Player Unit Interface Control Document (ICD), Consolidated Product Line Management (CPM), Graphical User Interface (GUI) Framework, and LT2 HCI Style guide. The LT2 standards provide industry the appropriate development guidelines and interface definitions in order to maximize industry involvement in developing product line solutions and providing advanced training capabilities through technology insertion. This paper provides an overview of how government and industry worked together to establish the LT2 standard initiatives based on common LT2-FTS use cases and details the relevant solution sets resulting in achievement of the PEO STRI mission and the LT2-FTS product line interoperability and reuse objectives.
