Systems Engineering

ETSI provides systems engineering services that include requirements analysis, architecture design, interface definition, hardware/software integration, interoperability analysis, concept development and validation, and alternative design evaluation (to include cost/benefit and technological feasibility analysis).

The company’s strength lies in serving as a true independent agent, ensuring a consistency of performance among hardware and software engineering groups relative to system requirements.

Test & Evaluation

ETSI’s test and evaluation services include test planning, test procedure development (scripting, particularly to testable requirements), test monitoring and conduct, test results analysis, and after-test reporting. The company’s testing approach begins with requirements-based test planning and progresses through test conduct and post-test analysis.

ETSI recognizes that testing is a quality assurance activity. Therefore, test plans and procedures are carefully reviewed for requirements traceability, demonstration of major system functions, consistency with the overall project/program plan, and the identification of test resources and tools.

The ETSI team knows and uses the Planning, Execution, Analysis and Reporting (PEAR) phases.

Command and Control (C2)

ETSI has experience performing engineering and/or management services in support of the following systems:

  • Advanced Man Portable Air Defense System (AMANPADS)
  • Air Defense Systems Integrator (ADSI)
  • Common Aviation Command and Control System (CAC2S)
  • Communications Data Link System (CDLS)
  • Diagnostic Support Tool (DST)
  • Joint Interoperability of Tactical Command and Control Systems (JINTACCS)
  • Joint Range Extension (JRE)
  • Joint Tactical Information Distribution System (JTIDS)
    • Multifunctional Information Distribution System (MIDS) terminals
    • Network Design Facility (NDF)
  • Link 16 Environment Gateway Stimulator (LEGS)
  • Range Guardian
  • Theater Battle Management Core Systems (TBMCS)

ETSI also has experience with United States Marine Corps (USMC) ground systems like Advanced Field Artillery Tactical Data System (AFATDS), Command and Control Personal Computer (C2PC) and Joint Tactical Common Operation Picture (COP) Workstation (JTCW).

Fundamentally, our cross-discipline team’s expertise with Tactical Data Links (TDLs), test methodologies, and data analysis provide an important level of continuity during the test process. We provide easily-accessible and reliable institutional knowledge to all involved in the event. Further, we believe our T&E proficiency has been useful as we have been willing and able to help with ground system tests, and we have done well in supporting these systems that are not our primary expertise. We believe our long history with C2 Programs of Record equates to a stronger, more agile test environment.


ETSI can provide interoperability and message standards experience, including data analysis and protocol knowledge, encompassing US Message Text Format (USMTF), Tactical Data Link (TDL)-A, TDL-B, TDL-J, Ground-Based Data Link (GBDL), Ground-Based Data Link (Enhanced) (GBDL-E), satellite data link communication protocols, and Variable Message Format (VMF) data communications protocols. The company also has experience with the Beyond-Line-of-Sight (BLOS) systems, and intelligence data links – both ground-based and satellite.

We were recently celebrated for our work on the CAC2S and F-35B Lightning II digital close air support mission capability demonstration. Colonel Stinson, former Commanding Officer of MCTSSA, wrote a letter of appreciation praising the team’s subject matter expertise and the way they used that expertise on a system for which they had little experience:

"The team executed tasks at superior levels of diligence and excellence resulting in numerous significant findings under the challenging conditions of live flight which included: developing a systematic approach to evaluate VMX-1 and CAC2S program objectives within an abbreviated planning phase, working based on very limited knowledge regarding F35 capabilities. working dry-runs for local procedures, working within the one-hour window allocated to aircraft for on-station work, extensive coordination with pilots, working with Network Design Facility personnel to integrate systems into a mutually compatible LINK16 network, working all event coordination via RF voice communications, and dealing with several flight cancellations. 

Although none had extensive experience with AFATDS and VMF they aided the execution of the VMF message exchange using the same levels of diligence and determination assisting with radio communications, setup and working the CAC2S-JREAPC communications. Although AFATDS was previously advertised as incapable of communicating VMF via UHF, Mr. Rodriguez was able to demonstrate that AFATDS was capable of exchanging VMF using UHF between AFATDS and TLDHS." 

Our team brings experience and insight to the support we provide, even in systems for which we have little experience. We use our expertise to make connections that benefit systems across the spectrum.

Program & Project Management Support

ETSI can provide program management support services that include project planning, Plan of Action and Milestones (POA&M) development and tracking, Work Breakdown Structure (WBS) development, budget development and cost monitoring, contract performance criteria specification, technical meeting support, trade studies and program strategy development. ETSI has performed, or is performing, Project Management services for the State of California’s Child Welfare Services (CWS) Case Management System (CMS) and to its current efforts to upgrade the system into a web-based platform through its CWS/CMS New System (NS) Verification and Validation (V&V) efforts.

Writing & Editing

ETSI’s writing division provides services that have garnered numerous accolades. Specific capabilities include technical writing, editing, indexing, grant writing, copywriting, and professional communications. Efforts have included the development of a suite of procedural manuals for complex DoD IT systems; editing of IT systems user’s manuals; editing of Navy instructional material covering a multitude of disparate systems; instructional system design for numerous Navy systems; and editing and formatting of State of California Department of Health Services (DHS) Short-Doyle/MediCal Health Insurance Portability and Accountability Act (HIPAA) technical analysis documents as a subcontractor to Science Applications International Corporation (SAIC). ETSI worked as a subcontractor to Mantech Systems Engineering Corporation (MSEC) on a multi-year contract supporting the training efforts of the US Navy SPAWAR Institute; responsibilities of the company on this contract are to perform writing services supporting prime contractor training efforts. Work performed to date has included the editing of Interactive Courseware (ICW) and Instructor-Led Training (ILT).
