Flight Software & Systems Engineering

EFSI delivers high-conformance flight software and systems engineering for NASA, NOAA, and GOES, specializing in the complete mission lifecycle — from Pre-Phase A concept studies through Phase E flight operations. We bridge the gap between legacy mission heritage and the next generation of autonomous space architecture.

EFSI personnel have contributed to over 20 successful flight missions and currently provide critical support for the Roman Space Telescope, JWST, and the Mars Return (CCRS) mission. We are also pioneering AI-driven engineering and edge autonomy to accelerate development and enable onboard decision-making — see details below.

Proven Mission Heritage

A track record of delivering flight-certified software for NASA's most demanding missions.

Extensive Portfolio

EFSI personnel have contributed to over 20 successful flight missions, with experience spanning UML model-based development (JWST ISIM) and traditional architectures (LRO, MMS, ATLAS, Hubble).

High-Profile Leadership

We currently provide critical flight software and engineering support for the Roman Space Telescope, James Webb Space Telescope (JWST), and the Mars Return (CCRS) mission.

AI-Driven Engineering & Innovation

EFSI is revolutionizing mission development by integrating Agentic AI and LLM-assisted workflows to achieve “Faster, Better, Cheaper” mission objectives.

Intelligent Tooling

We utilize advanced AI-assisted coding approaches to accelerate open-source and non-project-specific tool development, reducing cognitive load and increasing development velocity.

Seamless Deployment

These innovations are architected as modular tools and edge processes that can be rapidly transitioned into closed, project-secured environments upon mission acceptance.

Autonomous Mission Logic

We are developing Agentic AI models capable of translating natural language scientific intent into hex-encoded CCSDS packets, enabling real-time, science-directed tasking.

Closed-Loop Edge Processing

By deploying AI models directly to specialized edge hardware, we enable missions to autonomously prioritize high-value science data and optimize resource allocation.

Closed-Loop Verification

Leveraging AI for the automated synthesis of unit tests and build-test suites, ensuring exhaustive coverage for complex software builds.

Workflow Automation

Intelligent automation of ground system telemetry and command databases, and programmatic management of on-board flight software tables to maintain perfect parity between space and ground segments.

Technical Differentiators

Digital Twin

Our containerized Digital Twin (equivalent to a hardware flatsat) compresses development schedules and enables rapid iteration without physical hardware.

High-Performance Edge Accelerators

We specialize in deploying generative models onto low-power edge processing units to perform real-time atmospheric and situational analysis directly onboard.

Deterministic Autonomy

We integrate Agentic AI frameworks within standard flight stacks to ensure that autonomous decisions remain traceable and compliant with spacecraft commanding protocols.

Architectural Security & Data Sovereignty

From an architectural standpoint, we prioritize security through localization. Our internal development of edge-based AI models ensures that mission-critical data remains within the local system's security boundary.

This approach maintains strict data sovereignty, effectively eliminating the attack vectors and latency bottlenecks inherent in cloud-dependent processing.

Edge-Based Security

Mission-critical data remains within the local security boundary — no cloud dependencies, no external attack vectors.

Board Support Packages & Boot Loaders

Expertise in developing kernel mode drivers, Board Support Packages (BSP), and boot loaders including Start Up ROM (SUROM) for flight hardware.

Hardware Manufacturer Partners

Direct subcontracting relationships with flight hardware manufacturers including BAE Systems, SEAKR Engineering, AiTech, and IBEOS.

VxWorks & Real-Time Linux

Kernel drivers for Wind River VxWorks and real-time Linux (Xenomai) — mission-critical RTOS platforms for flight applications.

FOGI-Lake Environment

Our spacecraft development environment leverages containers to build complete end-to-end systems for rapid flight software development and testing.
