A system for locating of objects in a three-dimensional space comprises: (a) an impulse radio network including at least three reference impulse radio units and at least one mobile position indicating apparatus; position information relating the impulse radio units is recorded by at least one indicating impulse radio unit; the impulse radio units are in communication; and (b) an affixing structure for affixing a respective mobile position indicating apparatus with a respective object. A respective mobile position indicating apparatus transmits an impulse radio identifying signal that is received by a receiving impulse radio unit. An indicating impulse radio unit cooperates with the receiving impulse radio unit in using the identifying signal for developing coordinate information for locating the respective mobile position indicating apparatus. The method comprises the steps of: (a) providing an impulse radio network including at least three reference impulse radio units and at least one mobile position indicating apparatus; position information relating the impulse radio units is recorded by at least one indicating impulse radio unit; the impulse radio units are in communication; (b) providing an affixing structure for affixing a respective mobile position indicating apparatus with a respective object; (c) transmitting an impulse radio identifying signal from a respective mobile position indicating apparatus; (d) Receiving the identifying signal by a receiving impulse radio unit; and (e) operating an indicating impulse radio unit in cooperation with the receiving impulse radio unit to determine the location of the mobile position indicating apparatus.
