About
The Zendir Engine is the asynchronous simulation core underpinning Zendir’s entire digital-twin platform, converting real-world spacecraft and mission data into actionable simulation insight. It is built for scale and endurance, supporting 1,000+ concurrently simulated assets and continuous runs of 4+ days, or hundreds of asynchronous simulations per minute for large-scale trade studies.
The engine models full-system spacecraft behaviour, including subsystem interactions and fault/failure injection, and ships with over 150 pre-built component and environment models covering sensors, actuators, power systems, communications and ground-station links, plus orbital, gravity, atmospheric and geomagnetic environment models with SPICE integration for ephemeris data.
It exposes an open, language-agnostic API with C2-compatible interfaces for real-time telemetry ingestion and analytics, and integrates with hardware-in-the-loop (HitL) and software-in-the-loop (SitL) test rigs, OpenC3 mission operations software, CCSDS-compliant data formats, and Unreal Engine for high-fidelity 3D visualization.
