Welcome to the fastest and simplest way to design missions, develop GN&C algorithms, and simulate your spacecraft.

INTRODUCING MODELSPACE

INTRODUCING MODELSPACE

INTRODUCING MODELSPACE

Space is HARD. You need top-notch simulation capabilities to design and develop your mission - but the current tools are expensive and unintegrated.
That’s where ModelSpace comes in.

Built for simplicity.

No certifications necessary. Develop and run simulations within minutes.

Designed for iteration

Conduct trade studies and iterate quickly with Monte Carlo built-in.

Scalable as you grow

A simulation tool that sticks with you from design through operations.

We’re ready to meet your evolving needs.


Auto-generate reports and charts

Save valuable hours of manual plotting and writing.

Extensible for Deep Space

Architect missions beyond LEO with ease.
