Troubleshooting Spacecraft Entering into the Reference Ellipsoid
The error shown below typically suggests the Spacecraft has impacted the central body. Once the propagation gets to the point that the Spacecraft hits/crosses the 'reference ellipsoid' (surface of Earth), FreeFlyer will throw an error. This could mean that your orbit is low enough that it is quickly decaying. A good way to verify this is to report Spacecraft.Height or create a 3D View to visualize the orbit. Below are also a few code snippets that you can use to troubleshoot your Mission Plan.
Error Message: The gravitational force could not be evaluated. The Spacecraft has entered the reference ellipsoid defined in the potential field file.

Code: Select all
Report Spacecraft1.Height;
Plot Spacecraft1.ElapsedTime, Spacecraft1.Height;
