Contracts and Experience
Expeditionary Fighting Vehicle(EFV) Test Development
- Assist with analyzing the feasibility of creating a TPS to test the Weapon Station Electronic Unit (WSEU) with the existing Test Plan. The Plan required communication between the Marine Corps TETS test equipment and the UUT using USB to RS232 and RS422 hubs.
- The Firmware Support Manual (FSM) and CIDs documents for several internal SRU including Vista Single Board VME computer, DY4 processor board, Natel Power supply were reviewed by a Computer Servants Engineer.
- Review of design requirements in the form of a Critical Item Specification for the Marine Corps Expeditionary Fighting Vehicles, EFV, Weapon Station Electronic Unit, WSEU.
- Identified outputs requiring high current loading resistors and designed a suitable load condition including selection of hardware, determination of heat sink size, placement and functionality. Part specifications were reviewed and heated load conditions were considered to define the power sizing of the load resistors. Loads were required for signals including 28V Mil Std 1275, +/- 15V, 5V, and 26V 400Hz outputs.
- Directed all aspects of the hardware selection and assembly of the first TPS unit.
- Cables were designed for intermediate system testing of some subsystems and final deliverable harnesses were reviewed and revised as needed.
- Fabrication of test hardware by a lab technician was directed, and checked prior to delivery.
Expeditionary Fighting Vehicle(EFV) Electronic Hardware Design and Support
- Support the PDRR risk mitigation prototype units that were being built. Review and develop corrective action plans for grounding problems, drawing discrepancies and COTS card communication issues with PDRR hardware.
- SDD prototypes were built and detailed design documents were studied, corrected where needed and placed under document control.
- Component engineers, design quality assurance, test and manufacturing engineers were contacted and presented with design documents to verify the design.
- Design information was acquired from SRU vendors to assist with the integration of many designs into one LRU design in order to complete the prototype builds
- Identify circuits and responses that deviate from specification.
- Define and author an engineering test plan that can be followed by technicians with little knowledge of the system to reliably test the CCA and LRU. . Several prototype units failed and Computer Servants used standard lab equipment to troubleshoot and identify failed parts or incorrect assembly processes.
- Troubleshooting included identifying upgrade mods required to bring an older VME backplane to operational readiness.
NMCI – Navy Marine Corp Internet
- Conducted Due Diligence survey and evaluation of computer systems, servers, infrastructure and software in Florida, North Carolina and Virginia naval stations.
- Surveyed E-Mail systems and software at US based east coast naval stations. Participated in authoring team reports including recommendations for privatization of naval computer systems, NMCI.
