E4 currently provides full-stack web cloud software development services to the Telemedicine & Advanced Technology Research Center (TATRC) (in support of the Army Medical Command’s (MEDCOM) Tactical Telemedicine – Enhanced (T2E) effort) that provides the front-line Army medical clinicians the ability to reach out and touch a specialized physician via telemedicine that is made available through the E4 developed Micro-Medical Data Cloud (MMDC) dashboard. The Concept of Operational (CONOPS) is that point-of-care patient monitoring devices, such as the Battlefield Assisted Trauma Distributed Observation Kit (BATDOK) or Tempus Pro, will establish communication over tactical data radios to transmit medical data and imagery and provide Voice Over Internet Protocol (VOIP)  capability to a mobile PacStar server with the MMDC installed. Once a downrange medical provider receives the call, they use the web browser over the internet to view the transmitted medical data and imagery, while communicating directly via VOIP to the front-line medical clinician.

E4 currently provides support to the Program Executive Office – Aviation (PEO – Aviation), Assured Airspace Access Systems (A3S) Product Manager (PdM) customer for the Tactical Airspace Integration System (TAIS) Shelter and Airspace Workstation (AWS) maintenance and sustainment. Tasks include production unit acceptance preparation, software requirements derivation, software design, development and test, system acceptance test procedure development, software defect report preparation and resolution, configuration management and control, hardware & software diagnostics and repairs, Cyber Security patching, and document preparation (e.g. Software Requirements Specifications (SRS), Interface Design Descriptions (IDD), Interface Control Documents (ICD), Software Design Descriptions (SDD) Software Test Plan (STP) and Software Test Descriptions (STD)). 

E4 currently provides project management, software development, system engineering, and interoperability test services to the Program Executive Office – Aviation (PEO – Aviation), Assured Airspace Access Systems (A3S) Product Manager (PdM) customer for the Expanded Airtrack Sensor Interface (EASI) system. The EASI system provides all of the interfaces for the external sensor/track inputs into TAIS and was developed for the A3S PdM as a lower-cost, Government–owned solution compared to the legacy higher per–shelter cost that included the commercial off-the-shelf (COTS) Air Defense System Integrator (ADSI). E4 developed the EASI System by evaluating and eventually integrating two existing Government-owned systems. 

E4 currently provides Joint Interoperability Test Certification (JITC) support to its A3S customers for the TAIS. Tasks include configuring hardware-in-the-loop (HWIL) live and simulated test beds, developing Service Level Test (SLT) procedures that verify all minimal receive, transmit, and display requirements per military standards (MIL-STD), and performing post-test data inspection and analysis for inclusion into delivered the test report. 

E4 currently provides hardware integration and software engineering services to the A3S PdM’s Tactical Terminal Control System (TTCS) to support the TTCS next-generation field release baseline. The primary objective was to integrate the existing EASI capability onto the TTCS fielded hardware to provide forward-deployed Air Traffic Controllers with an enhanced Air Traffic Situational Display (ATSD) consisting of sensor inputs from the Army’s Blue Force Tracker (BFT) system, a Passive Detection Reporting System (PDRS), and PM ATC’s Air Traffic Navigation, Integration, and Coordination System (ATNAVICS) Air Surveillance Radar (ASR) and Precision Approach Radar (PAR).      

E4 played an essential role in the A3S PdM TAIS Block Upgrade (BUG) 1+ Shelter Material Work Order (MWO) effort, which attributed to not only meeting a firm fielding schedule, but also achieving PM ATC’s per-shelter budget. Tasks performed included hardware selection and integration, blade server configuration, VMWare architecture deployment, network design and configuration, and technical manual development while applying Capability Maturity Model Integration (CMMI) processes and following the United States Communications-Electronics Command (CECOM) requirements for formal material release.

E4 provided PEO – Aviation with system engineering and design support for the Electronic Flight Strip Management System (EFSMS).  The EFSMS application provides Air Traffic Controllers (ATC) with an automated capability to create, update, send, and receive Federal Aviation Administration (FAA) Form 7230-21 flight progress strips, which will ultimately replace the current methodology of manually generating the forms. Furthermore, E4 is currently working with SED to deploy the EFSMS application onto a forward-facing Cloud-based Web Server to provide CONUS-based active ATC operator access to the application for real-time mission use.

E4 currently supports PEO Aviation with CMMI Decision, Analysis, and Resolution (DAR) services for new technology evaluations and insertions to existing fielded product lines. This includes test and analysis activities that compare technology options and provide recommended solutions based on customer-stipulated rating criteria.

Other E4 past performance includes six years with Independent Verification and validation (IV&V) support to the PEO Missiles and Space (M&S), Cruise Missile Defense Systems (CMDS) Joint Land Attack Elevated Netted Sensor System (JLENS) Project Office for JLENS Spiral 2 development and fielding. Services provided included system engineering, software analysis, software and hardware integration, and interoperability testing throughout the JLENS Sprial 2 system life-cycle.
