[Gmat-developers] Is there a repo of GMAT tutorials with various mission scenarios - or GTO > GEO ?

I’m interested to use GMAT model a electrically pulsed vacuum arc thruster system with very high Isp (I developed such a system for earlier Cubesat space missions which have flown) module definition in GMAT. I was thinking it would be interesting to try to “fly” a Geosynchronous Transfer Orbit (GTO) to GEO parking, GEO, or GEO Graveyard orbit for a SmallSat.

 

My thoughts are:

 

1. Deployment from the launch vehicle on the GTO trajectory, plus a little bit of motion in 3-axis due to the deployer of the SmallSat
2. Account for very little drag, but perhaps effects due to solar pressure?
3. Take reading from the navigation and attitude determination system
4. Fire engines to form a combined plane change and altitude adjustment for a bit and coast.
5. If not reached waypoint, repeat 3-4.

 

At that altitude, do we have any gravity manifolds to take advantage of by going to any nearby vicinity with the intention of getting back to GEO graveyard?

 

Thanks.
