That depends on the circumstances of your case. Based on how you describe the situation it could happen that you get deported even if the court hasn't made a final decision on your case yet.
If you do a second application for asylum (a so-called "Asylfolgeantrag") BAMF usually rejects it. You can appeal against that (which you already did), but you have to file a so-called "Eilantrag" at the same court to postpone an imminent deportation. It's recommended to consult a lawyer for legal support in such cases. If you don't file an "Eilantrag" (or if it gets rejected) you can get deported before receiving the decision by court.
