Your guide to the best, most reliable flight dynamics software begins here.
Flying today's most exciting missions
International Space Station
FreeFlyer computes all the flight dynamics for daily operations of the International Space Station (ISS).
JWST
FreeFlyer powers the JSWT Flight Dynamics Ground System and performed launch window and insertion maneuver analysis.
Lunar Gateway
NASA uses FreeFlyer to optimize Gateway's NRHO and to model atittude for power and communications planning.
Dream Chaser
FreeFlyer, Meridian and Atlas are the backbone of the flight dynamics ground system for Dream Chaser.
Magnetospheric Multiscale
FreeFlyer powers complex maneuver planning to maintain the 4-satellite tetrahedron in a highly elliptical orbit.

Next generation script editing
Type less, analyze more.
FreeFlyer's scripting environment does more than let you control the inputs, outputs, and logical flow of your simulations. It empowers you to innovate. Imagine scripting a custom model for solar panel energy output that aligns precisely with your mission's parameters. FreeFlyer makes this possible, providing a platform where the only limit is your imagination. FreeFlyer 8’s all-new parser and code editor make scripting faster and easier than ever before.
Run fast with FreeFlyer Script
Build sophisticated mission sequences modeling the operations of your mission with our full-featured scripting language. The new Command Palette puts everything at your fingertips - all script editor functionality including keyboard shortcuts can be explored and triggered here.
Powerful new productivity boosts
Auto-complete matches text in any part of the word. Docstring support is expanded to user-defined Procedures and parameters, Structs and fields, and more.
Smart suggestions for error resolution
Identify and quickly resolve issues with new context-aware suggestions. Scan and report on all errors in a document in a single pass.
Lightning fast visualization
No bottlenecks between you and your results.
FreeFlyer 8’s rendering engine uses an all-new, non-blocking graphics pipeline so the astrodynamics engine can run faster than ever.
Integrates with your tool suite
Embed FreeFlyer in workflows from mission concept to operations
FreeFlyer Runtime API
Automate FreeFlyer execution from Python, Java, C/C++, and C#.
The FreeFlyer Runtime Application Program Interface (API) empowers organizations to seamlessly integrate advanced astrodynamics capabilities into their existing systems. By enabling programmatic execution of FreeFlyer Mission Plans and scripts, the API supports applications such as real-time ground system integration, streamlined data management, and enhanced automation workflows. It facilitates distributed processing, allowing tasks like database queries or socket communication to be offloaded to host applications while FreeFlyer engines run asynchronously. This flexibility makes the FreeFlyer API an ideal solution for mission operations, space situational awareness, and other complex aerospace applications requiring efficient, scalable, and customizable solutions.
