A GPS positioning and returning device is provided. The GPS positioning and returning device comprises a compass, a GPS module, an input interface, a memory, a display module and a control module. A marked direction on the GPS positioning and returning device pointing to the cardinal point of North on the compass is a reference direction. Through an input from the input interface, a first control signal is generated. The first control signal is received by the GPS module through the control module so as to generate first coordinates; the first coordinates are then stored in the memory. The input interface may further input a second control signal. The second control signal is received by the GPS module so as to generate second coordinates. After a relative direction and distance between the first coordinates and second coordinates are calculated, the display module is driven to display the relative direction and distance.
