Create an orbit modeling object

Choose Home tab→Loads and Conditions group→Modeling Objects .

  1. From the Type option list, select Orbit.

  2. Click Create.

  3. In the Orbit dialog box, in the Properties group, select a celestial body from the Planet list.

  4. From the Orbit Type list select a predefine orbit or Classic to define all classical orbit parameters.

  5. On the Spacecraft Attitude tab, in the Orientation Options group, define the required vectors to orient your model.

  6. On the Orbit Parameters tab, set all the classical orbit parameters that define your orbit.

  7. (Optional) On the Sun Planet Characteristics tab, review or set the sun and celestial body constants.

  8. (Optional) On the Calculation Positions tab, define orbit segments, parent orbits, number of calculation positions and their occurrences.

  9. Click OK.

  10. Click Close.
