Positioning device and method for measuring the distance between multiple positioning devices

摘要

A positioning device includes an antenna, a receiving module, a processing module and an output module. The receiving module receives positioning signals transmitted from positioning satellites and a position signal of another positioning device transmitted from a ground monitoring system 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 another positioning device. The output module outputs the distance. A method for measuring the distance between the positioning devices is also provided.
