hyperbolic trajectory
Anyone have a good website for how to determine the position along
hyperbolic trajectory(or what elements needed to calculate it, e.g velocity at perigee, radius...), I just read through the notes about determine the position along the elliptical orbit, but notes doest say how to calculate it for hyperbolic trajectory. |

Wikipedia seems to have the answers you're looking for. I don't know whether they are correct of course... -- Mark Real email address | Keep your words soft and tender, is mark at | for tomorrow you may have to eat them ayliffe dot org | |

I found the equations for the problem its just similar to kepler's equation for ellipse. does anyone know how long does it take for a spacecraft to reach the Sphere of Influence point on a hyperbolic trajectory using small delta- v 's ? |
