Positioning information sending method, positioning track drawing method and positioning system

The invention provides a positioning information sending method, a positioning track drawing method and a positioning system. The positioning information sending method can comprise the following steps: acquiring positioning information of a plurality of positioning sub-modules and information identifiers corresponding to the positioning information; calling the fusion sub-module to perform fusion processing on the plurality of pieces of positioning information, and generating positioning fusion information and a target information identifier corresponding to the positioning fusion information; and sending the positioning information, the information identifier, the positioning fusion information and the target information identifier to a trajectory drawing module, so that the trajectory drawing module draws positioning trajectories corresponding to the plurality of positioning sub-modules according to the information identifier and the positioning information, and draws the positioning trajectories correspon
