Digital Engineering Built for Production.
We don’t just "model" for the sake of documentation. We engineer digital ecosystems where every element is computed, validated, and integrated.
Our Core Capabilities
Utilizing SysML and UAF to build models with machine-readable semantics, moving beyond "drawing blocks" to "executing logic."
High-Fidelity MBSE:
Connecting the "Digital Thread" from high-level Government requirements (DOORS/NextGen) to low-level system verification.
Total Traceability:
We treat the modeling environment (Cameo) like a software IDE, using scripts and plugins to eliminate manual data entry.
Automation-First Workflow:
Advanced Framework Mastery
SysML Transition: Helping programs leverage its new API-first architecture and textual notation for better tool interoperability.
DoDAF & UAF Experts: Delivering the complex views (Operational, System, Capability) required for DoD compliance, but keeping them interconnected so a change in one is reflected in all.
MOSA Compliance: Engineering for the Modular Open Systems Approach, ensuring system architectures are truly open, modular, and vendor-neutral.
Whatever you're building, we're here to help you take the next step with confidence.
Toolchain Mastery &
Automation
Cameo Platform Transformation:
1
Custom Plugin Development: Building tailored software extensions for Cameo/MagicDraw to add custom workflows and analysis features.
Validation & Governance: Implementing automated OCL (Object Constraint Language) rules to catch "broken traces" or "orphan requirements" instantly.
Automating the ingestion of structured text, interface definitions, and legacy documents into valid SysML elements.
2
Text-to-Model Pipelines:
Automated Report Generation:
3
One-click generation of full architecture report packages (Word/PDF) for milestone reviews (PDR/CDR), ensuring the "document" always matches the "data."
The Digital Thread & Digital Twin
Frameworks & Operational Intelligence
At Northgrid, we don't treat a Digital Twin as a static 3D model. We define it as a dynamic, virtual replica of a physical system, synchronized by a continuous digital thread. By bridging the gap between conceptual architecture and live operational telemetry, we enable organizations to monitor, predict, and optimize performance throughout the entire system lifecycle.
Integrated Sensor-to-Model Orchestration: We design frameworks that ingest real-time data from physical assets via IoT protocols (such as MQTT or AMQP), mapping telemetry directly to SysML block properties.
Virtual Commissioning & HiL: Using the Cameo Simulation Toolkit, we execute Hardware-in-the-Loop (HiL) simulations that allow you to test control logic against virtual architecture before physical hardware is even available.
Predictive Performance Margins: Our frameworks use parametric engines to compare "as-designed" performance against "as-operating" data, identifying drift and predicting maintenance needs before they result in mission failure.
What-If Scenario Execution: We build "executable" digital twins that allow engineers to run high-fidelity simulations of operational contingencies, such as orbital debris avoidance or power-loss recovery, within a risk-free digital environment.
