    And with Ken Ernandes' VEC2TLE you can do it three ways:
    Find velocities (and position, in three directions) from any orbit at any
    given time.
    Find the orbit from given position and velocities.
    Find the orbit from an initial orbit and velocity change.
    (Use i=0, RAAN=0 and AOP=0 to make working with absolute velocities and
    perigee/apogee easier)

    So does TRACK16.
