- Propagate an orbit.
- Transform orbital elements to state vector
- Transform state vector to orbital lements
- Solve Kepler's equation M=E-eSin(e) for an elliptical orbit
- Transfer between two circular orbits
- Compute velocity impulse for plane change
- Approximatley estimate an orbit from
two position vectors and time.
I plan to add more utilities. Please bookmark and visit again. If you are looking for a good book on orbital mechanics visit the recommended-books store.
