1. A terminal location system having at least (N+1) base stations, wherein N is in the range of 1 to 3, wherein a terminal location server finds a position of a terminal performing wireless communication in N-dimensional coordinates, and wherein relative coordinates among the at least (N+1) base station are calculated, comprising:

  • a calculation of relative coordinates among the base stations;

    an evaluation of the obtained relative coordinates; and

    a switch to terminal location processing for determining the position of the terminal;

    wherein the determining of the position of the terminal comprises using propagation times of radio signals transmitted and received between the terminal and the base stations in accordance with the evaluated, obtained relative coordinates of the base stations.
