Thank you, matth! I'm sorry, but i put a wrong link under  spoiler, now i put the right one. This is because that the libraries described in both articles are equally interesting to me. Take a look again, please.

I message them on facebook, but receive no answer. I can't find email adress in article or in other sources.

Dear all,

Through my course work i need to calculate link beetween satellite and ground station budget as one of the task. I do this with MS excel. But  when i meet modelica and read paper about SpacecraftLib, i was very interested to use modelica in link calculating. But till this moment i no idea where i can get it.
