About initial conditions

  1. Jul 23, 2007 #1
    Hi guys, help me.

    I have a code for integrate the equations of motion of three bodies in a inertial frame, and in cartesian coordinates (x, y, z, vxi, vyi, vzi), i=1,2,3.
    The question is, how can i use the data of JPL Horizons to obtain positions and velocities in a inertial frame? :surprised
