hey have ben doing orbital mechanics a long time, I usually use GMAt. I do not like yuour software, it is impossible to create a good ephemeris file. And to be frank with you guys, you have had this software out for almost 25 years, and GMAT is easier to use than your software. When are you actually going to fix this software? i have ben asking for this feature a long time. I'm not sure what i am paying you guys for anymore. I should not be using freeflyer, i should not be using a custom script i wrote, I should click a button and tell STK to generate a cartesian, AzEl, or any other format i want. Instead i get a 38 minute tutorial that i can do in GMAT in 2 minutes. Pretty embarrassing, trust me.
