I hope there is someone who can do the conversion, Petittrack is ideal for actual satellite communication on a handheld device as it also shows a sun and moon as sky landmarks to help aim your antenna. I used to attach both my true dual band VHF/UHF Alinco DJ-580T and my Zaurus SL-5500 on the yaggi antenna mast to help me aim and track, Petittrack also helped me tune the relativistic Doppler radio frequency shift coming and going.
Here is a list of sats you can play with and their reported status
