Propagate Orbit


Here you can propagte the orbital elements of a spacecraft in orbit starting from an initial time ti to tf=ti + delta-t Please Enter the Orbital Elements (all angles in degrees) at ti below:

Semi-major axis(Kms): Eccentricity:
Inclination: Arg of Perigee:
Right Asc of Asc Node: Mean Anomaly: Time Delat-t Select model:

The propagated values are as follows

Right ascension of ascending node
Argument of perigee
Mean Anomaly

The components of the state vector are as follows

Position vector(x,y,z)in Kms




Velocity vector(x-dot,y-dot,z-dot)in Kms/sec
