Zendir builds training, rehearsal, and automation tools for satellite ops teams. Using high-fidelity digital twins and cloud-scale simulation, we rehearse high-consequence missions, quantify risk, and speed the path to flight. Supports scenario-based training, ground/flight software integration, constellation analysis, and fault/threat injection (anomalies, cyber, GNSS disruption, contested-space). Integrates with existing C2 workflows and produces repeatable, defensible results.

Zendir Editor: Digital Twin Sandbox for Engineers Zendir Editor is a high-fidelity spacecraft and constellation modeling environment for engineers building, validating, and iterating mission concepts and subsystem behavior. It enables teams to construct "system-aware" digital twins (power, ADCS, comms, payload, etc.), explore edge cases, and run repeatable what-if analyses with clear assumptions and outputs. Editor is designed to support collaboration across distributed teams, accelerate verification and validation cycles, and produce results you can defend in reviews.
Key capabilities
- Subsystem-aware modeling for spacecraft and fleets
- Scenario configuration for nominal, off-nominal, and stress cases
- Repeatable simulation runs with parameter sweeps and comparisons
- Outputs that support engineering review workflows and trade studies
- Integration-friendly architecture for existing tooling and data sources Common use cases
- Digital engineering & V&V support
- Constellation design trades and performance threshold testing
- Failure mode exploration and operational limits definition
- Pre-flight readiness analysis and rehearsal inputs
Zendir Studio: Operator-Focused Mission Configuration & Training Zendir Studio is a drag-and-drop environment for configuring missions, running scenarios, and supporting operator training and rehearsal. It's designed for operational roles-making it simple to stand up realistic training sessions without requiring deep modeling expertise. Studio supports instructor-controlled runs, repeatability across cohorts, and structured outputs suitable for after-action reviews and decision support.
Key capabilities
- Drag-and-drop scenario and mission configuration
- Instructor-controlled injects (anomalies, disturbances, operational constraints)
- Role-based views for operations teams and trainers
- Repeatable sessions for skills sustainment and evaluation

- Team coordination drills and procedure validation
- After-action review and lessons-learned capture
Zendir API: Cloud-Scale Simulation & Integration Layer Zendir API is a REST-based simulation interface for running spacecraft and constellation simulations programmatically at scale. It enables customers and partners to integrate high-fidelity simulation into existing pipelines-CI/CD, digital engineering workflows, autonomy development loops, and mission planning systems-without being locked to a single UI. The API supports repeatable runs, automation, and integration with customer data and toolchains.
Key capabilities
- Programmatic scenario execution and results retrieval
- Scalable simulation runs for parameter sweeps and batch studies
- Integration hooks for external systems and data sources
- Designed for automation, testing pipelines, and platform embedding
- Supports building custom applications and portals on top Common use cases
- Large-scale trade studies and regression testing
- Autonomy development & evaluation loops - Integration with mission planning / analysis toolchains
- White-label simulation services for primes and integrators
Highlights
- Zendir Studio (Operator Simulation Layer) Zendir Studio is an operator-facing mission control and training environment built on high-fidelity digital twins. Teams configure missions, rehearse maneuvers, inject anomalies, and run multi-satellite scenarios in real time. Powered by Zendir Core, Studio transforms engineering-grade models into interactive operational capability for mission rehearsal, training, and anomaly response.
- Zendir Editor (Engineering Creation Layer) Zendir Editor is the engineering environment for building high-fidelity spacecraft and mission digital twins. Engineers model subsystems, onboard logic, and physics interactions, and run software and hardware-in-the-loop testing in closed loop. Editor enables rapid digital twin development and deploys validated assets directly into Studio for operational rehearsal and training.
- Zendir API - Pacer (Automation & Integration Layer) Zendir Pacer API connects live mission operations to Zendir's Core digital twin engine. It ingests telemetry, mirrors maneuvers, and enables on-demand simulation for forecasting, anomaly reconstruction, and performance validation. Pacer provides real-time operational intelligence through calibrated digital twins, supporting automation, risk reduction, and informed decision-making.

Version release notes
This release includes the v1.6.0 versions of Zendir Studio, Zendir Editor and the associated Zendir API Python scripts. The major changes across the software include:
Rendezvous & Proximity Operations (RPO):
- Developed custom flight software to support RPO approximations between two spacecraft, enabling rendezvous via external force modeling.
- Added docking adapter components with visual alignment guides to support physics-based docking operations.
- Introduced an external force component to simulate maneuvering strategies, including V-bar, H-bar, and perch formation flying modes.
- Implemented visualization of relative spacecraft positioning, allowing orbital relationships between two objects to be displayed in real time.
Space Range:
- Developed an advanced Space Range UI enabling full scenario configuration, including teams, component parameters, events, ground assets, and spacecraft orbits.
- Implemented a multi-asset management system, allowing teams to control multiple spacecraft and assign assets across teams for competitive RPO scenarios.
- Integrated CCSDS-compliant packet structures for spacecraft telemetry, with support for requesting XTCE packet definitions to ensure compatibility with external C2 systems.
- Added packet inspection capabilities with anomaly simulation (e.g., data corruption), along with visualization tools for byte-level analysis.
- Enabled full RPO functionality within Space Range, including docking, maneuvering, and thruster operations.
- Expanded administrative tools to support historical data retrieval, simulation trigger configuration, and event data access.
- Updated the standard Space Range operator C2 sample tool to improve usability and streamline scenario interaction.
Power Systems:
- Implemented a UI-based network graph editor for designing both simple and complex power systems. This allows users to construct circuits by adding components such as diodes, loads, sinks, switches, fuses, and voltage regulators in both series and parallel configurations.
- Added real-time visualization of power flow direction and live telemetry data, including voltage, current, and resistance for each component.
- Introduced support for electrically controlled power motors.
- Updated computer-based power models to automatically shut down when power levels fall below operational thresholds.

- Resolved major plotting issues, including database persistence, data reset behavior, line color rendering, and property removal handling.
- Introduced scatter plot support alongside existing line and bar chart options for improved visualization of noisy datasets.
Custom Mesh Designs:
- Added functionality to simplify component meshes into primitive geometric shapes (boxes, ellipsoids, cones, cylinders, and capsules) to streamline spacecraft design and visualization.
- Introduced a UI color palette with support for precise hex-based RGB color selection.
General:
- Enhanced component selection behavior, including displaying component labels on hover.
- Added UI-based scaling controls for spacecraft and component visualization.
