Trajectory lines for two satellites maneuvering around Earth - scales in meters

Kozmoworks is an astrodynamics and space mission simulator. This version features an 8th order symplectic orbit propagator and currently supports n-body problems with:

• impulsive orbital maneuvers
• finite burn orbital maneuvers of constant acceleration type
• atmospheric drag effects
• radiation pressure
• spherical harmonics gravity field models

Some lower priority features are yet to be implemented:

• Relativistic effects
• Complex propulsion and attitude simulations (incl. gravity gradient torque and the like)
• Spacecraft power and systems management
• Additional physics integrator/propagator options
• Built-in 3D visualizations
• Graphical scenario editor

Mission scenarios are defined in .json files - see scenarios/test.json for an example.

Kozmoworks is also the successor to OrbitSim3D, a space mission simulator written entirely in Python, using pyOpenGL - check it out if you like!
