Frequently Asked Questions
Can the component models be customized to match my spacecraft's components?
Yes. Studio and the API both draw from the same library of real, physics-based components, and any of them can be configured or swapped to reflect your spacecraft's actual hardware.
Is this an actual digital twin, or just a simulation?
It's a digital twin — a physics-based model of your spacecraft and its environment that can be updated and re-run as your mission design or operating conditions change, not a one-off simulation run.
What's your verification and validation process?
Every release goes through code review and a suite of 800+ unit, integration, and system tests, with results benchmarked against tools including STK, Basilisk, and AI FreeFlyer. Zendir is also ISO 9001 certified.
Does it run on Linux?
Zendir Studio currently requires Windows. The Python SDK is Linux-native and can build and run simulations without Studio's visual interface — if you need the full graphical interface on Linux, running Studio through Wine is currently the only option.
Can I integrate with my own protocol or packet format instead of CCSDS?
Studio's built-in messaging model is CCSDS-based. If your systems use a different protocol, the API gives you direct, programmatic access to build a custom integration.
Can I use my own command-and-control (C2) or ground system instead of Zendir's?
Yes — Studio and the API are designed to integrate with external ground and C2 systems rather than requiring you to replace your existing tooling.
Does it support domains outside space, like maritime?
Some — maritime support already exists today. Broader multi-domain support is an active area of development.
Can I deploy on-premises or in an air-gapped environment?
Yes, on-premises and air-gapped deployments are supported, and are commonly used in defence and other security-sensitive environments.
Can I automate simulations without opening the Studio interface?
Yes — a build created in Studio can be exported to the API, so you can keep Studio's drag-and-drop assembly for design and then automate and scale runs programmatically from there.
How is Zendir different from other simulation tools like STK?
Zendir is built around an intuitive, modern interface designed to get you from concept to simulation quickly, without requiring deep simulation-engineering expertise — while still giving engineers full programmatic control through the API when they need it.
