Abstract
A relative position positioning system and a relative position positioning method thereof are disclosed. The method includes the following steps: controlling a plurality of receivers to broadcast a plurality of positioning signals; receiving the plurality of positioning signals and then returning a first reply signal; controlling a plurality of first receivers to transmit a first positioning data to a main device to calculate the plurality of distances to the plurality of first receivers, wherein the plurality of first receivers are devices that have received the first reply signal; returning a second reply signal from the device of interest; controlling a second receiver to transmit a second positioning data to the main device, wherein the second receiver belongs to the plurality of first receivers and has received the second reply signal; and calculating a relative position relationship between the main device and the device of interest.
