摘要

"Systems for locating and tracking a mobile controller of a mobile controller and for locating a mobile controller for an operable mobile controller with a radio communication network, and method for locating a mobile controller and a mobile controller" . A mobile controller unit (200) has a radio positioning system (204) and a two-way communication system (202) and a traveling unit (214) also has a radio positioning system (218) and a radio positioning system. two-way radio communication (216). The controller unit 200 may request the traveling unit 214 to send its location data so that the traveling unit can be located, and if desired, found, such as in the case of a lost child or items. . Relative position between controller and rover can be displayed (208) on the controller along with an arrow showing where the rover is, as well as how fast it is moving, a track of its movement and other data. The system may also operate in conjunction with a network system (212) which has a PDE and an application server (210) that perform some of the communication and calculation functions.
