In What are the choices today for orbital mechanics simulation software?, an entire range of software was listed for many platforms. I'd like to narrow this down a bit. Specifically, two questions:

  1. Which of these software packages, if any, can perform trajectory analysis for deep-space probes, including calculating gravity assists?
  2. For those of you familiar with NASA's Copernicus trajectory analysis package, how do these compare?

"Deep-space", for the purposes of this question, includes currently known Trans-Neptunian Objects (TNO). Also, you need not limit yourself to the specific packages mentioned in the above referenced question.

  • $\begingroup$ Some self advertisement can't hurt, right? :) Anyway, that's in MATLAB. AFAIK, many of the tools used in any sort of professional context are home grown and usually very specific. The market is also not big enough to justify development of a generic, user-friendly software package. I've heard STK does a reasonable job, but I don't have personal experience here. $\endgroup$ – Rody Oldenhuis Feb 18 '14 at 12:51

The software used for this at JPL is all homegrown. A great deal of effort goes into the optimization algorithms for complex, multi-body and/or low-thrust trajectories. You can try to request tools here. Examples are CATO, Mystic, and MALTO. However these tools are not really intended to be "user friendly", and require a great deal of domain expertise to operate.

a.i. solutions (www.ai-solutions.com) has multiple tools that handle space mission design. Their high fidelity FreeFlyer is directly comparable to STK/ODTK in every way and is used for many NASA and USAF missions. For Deep Space trajectory design like described above they also have a complementary visual tool called the Deep Space Trajectory Explorer which is being built to be very simple to use. It handles Lagrangian Halo, P2 centered Ballistic and Asteroid centered trajectories.
