11. interference source in up going route positioners as described in claim 9 or 10, it is characterized in that, described locating module, specifically for be subject to same interference source described in transferring to according to the interference signal propagation loss that is respectively disturbed community, the receiving belt internal power that is respectively disturbed community affecting and the horizontal direction angle that is respectively disturbed community, calculates the positional information of described same interference source.
