Our Expertise

T2 Core Competencies

Our engineering and integration support defines system performance and identifies system configurations for the development and/or modification of Army test measurement and diagnostic equipment (TMDE), test programs sets (TPS), automatic test equipment (ATE), automatic test software, and built-in self-test (BIST) systems. We fully understand that these efforts involve the analysis of system operational characteristics, mission objectives, threats, environmental factors, etc., and systems engineering and integration support from the development and demonstration phase through production and in-service support for fielded systems.

WE PROVIDE:

  • Systems integration and engineering
  • Test and evaluation
  • Configuration management
  • Publication support
  • Logistics support
  • Weapons system development and support
  • Design and development of TPS software and hardware

Case Study

CUSTOMER CHALLENGE

The U.S. Army Armament Research, Development and Engineering Center (ARDEC) requires the design and development of automatic test system (AT-System) and on-board system test kits to augment weapon system fault detection and fault isolating test requirements. Weapons systems in need of these services include the Paladin M109A6/M109A7 Self-Propelled Howitzer and its Diagnostic and System Health (DASH) module.

OUR SOLUTION

We designed AT-System kit hardware using computer-aided design (CAD) software for 3D modeling of interface device (ID), cabling, and test fixture/adapter designs. Our extensive inventory of components and parts were cataloged and made accessible via state-of-the-art inventory/production management software to adjust build schedules and maximize operating efficiency. Our highly detailed technical data analyses for each individual system component aided in test strategy development. The test strategy incorporated links to the DASH system that performed onboard embedded background monitoring to interrogate line-replaceable unit (LRU) built-in test (BIT) results and initiated BIT (IBIT) results. The strategy also incorporated design reviews and acceptance testing requirements for each diagnostic procedure.

HOW WE INNOVATE

We developed a Wired/Wireless Acquisition Module (WAM) to provide the automated capability necessary to provide LRU signal stimuli and measurement capabilities. The WAM provided forty fully switchable multi-purpose I/O channels, ethernet, and serial ports, as well as weapon system maintainers with diagnostics that isolate system failures to a single repair item. This resulted in great cost savings at the unit level and potentially eliminated no evidence of failures (NEOFs) at the depot level.
