Plotting Heliocentric Orbits

Using GMAT for specific types of missions.

Plotting Heliocentric Orbits

Postby joertexas » Wed Mar 24, 2010 8:40 pm

Does GMAT handle heliocentric orbits? I'm trying to design an asteroid mining mission, and I'm having no luck with GMAT. Also, is there a way to display time enroute and total Delta vee for a trajectory?

I'm a complete beginner at this, so it's a steep learning curve for me...

Hi,
As for plotting heliocentric trajectory:
1 - create a sun-centered coordinate system (Coordinate Systems -> Add Coordinate System -> Origin Sun, type MJ2000E*)
2 - in Subscribers, add an Opengl plot, and in the view definition select the newly created coordinate system.

This is how I do it, but there may be other solutions.

For the other plots, using a XYPlot, you can plot for instance the TotalMass (~DeltaV), and use ElapsedDays, ElapsedSec, or ****Julian

Ok, I managed to have a lunar impact landing...
I'm still having some problems to achieve zero velocity at touchdown.
I know that it's possible using a finite burn, but it's not so clear how to use it in the code.

Did you manage to obtain something?

Thank you very much for your help and time.
