Guys, today was flight from Budapest, gate 34. I entered GPS position in FMC and compared it with gate coordinates at the placard over the gate number. I was confused! GPS shows coordinates N47.25,9 But placard says, that gate coordinates N46.25,9. One degree latitude difference!!! I cheked it in jeppesen chart - N47.25,9. So, that's why i always use GPS position or ARP from database in FMC.
