    Abstract: A lithographic apparatus including a moveable object (WT) and a displacement measuring system arranged to determine a position quantity of the moveable object. The displacement measuring system includes an encoder (BC) and a grid structure. One of the encoder and the grid structure is connected to the moveable object. The grid structure includes a high precision grid portion (HG) and a low precision grid portion (LG). The encoder is arranged to cooperate with the high precision grid portion to determine the position quantity relative to the grid structure with a high precision. The encoder is arranged to cooperate with the low precision grid portion to determine the position quantity relative to the grid structure with a low precision.
