Zendir Software Suite

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
• Clear run artifacts for debrief and learning outcomes Common use cases
• Scenario-based operator training
• Mission rehearsal before critical events (deploy, commissioning, RPO, contingency ops)
• 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
