I hope this comes through with the language barrier.
Why are you using the name "Antigravitic Systems"?
By using the prefix, "Anti", you are stating the opposite of the term "Gravitic".
Gravitic has been identified as the study of applying the force of gravity, to do work. The suffix "ic" is used to identify "that which or pertains to". For example, the work "electron" has the suffix "ic" added to make "electronic", that which pertains to electrons in doing some form of work.
So, using the term "anti" with the term "gravitic" is opposite to what it is. Do you really mean to state "anti gravity"?
Thus your site would be "Anti Gravity Systems" which is more on point, I would think. "Anti Gravitic" , in the manner I see you apply it would be the opposite of what a gravitator does.
I hope this translates well. I am just attempting to understand.
