Spacecraft visibility from Earth

Postby adrimorabo » Mon May 12, 2014 2:28 pm

Hi everybody! my name is Adrian and I am just getting started with GMAT.

In my mission, I have a satellite orbiting around Mars and I would like to know (via GroundTrackPlot or data file) when are the visibility windows of my satellite from Earth, as there will be moments when Mars is blocking the satellite's line of sight.

I haven't found any specific function for that. I reached to do the tracking of the satellite printed on Earth, but it also does the tracking when it is "behind" mars (Earth-Mars line of sight).

I hope you understand my question and I wait for an answer from you expert guys!

Thank you very much in advance!

Hi Adrian,

GMAT currently doesn't have anything built-in to do visibility. That's something we're currently working on though.

If you know the math to calculate it, you can code it up in the script, though.
