Abstract:
A positioning device includes an antenna, a receiving module, a processing module and an output module. The receiving module receives positioning signals transmitted by positioning satellites and a position signal of another positioning device using the antenna. The processing module determines a position of the positioning device according to the positioning signals, and calculates a distance between the positioning device and another positioning device according to the position signal of the position device and the position signal of the other positioning device. The output module outputs the distance. A method for measuring the distance between the positioning devices is also provided.
