A global positioning system device and an ionosphere error estimation method thereof are provided. The global positioning system device is connected to a plurality of dual-band base stations, and receives a plurality of ionosphere pierce point coordinates and a plurality of ionosphere errors from the dual-band base stations. The global positioning system device calculates a user ionosphere error by an interpolation method based on the ionosphere pierce point coordinates and the ionosphere errors of the dual-band base stations and a user ionosphere pierce point coordinate of the global positioning system device.
