[Pallmall68]

it is possible that position of a plane is false? Because sometimes I have planes which landing at 1nm of the airport (LSGG).

Thanks.

Yes. the ADS-B position information is sent by aircraft is determined by its GPS system or INS system. If the latter is used it is sometimes inaccurate which leads to positions being out by a common factor.
