Definitions

  • GPS Global Positioning Systems
  • radio beacons tri- angulation via radio beacons
  • cellular telephone auto-location there is clearly a problem in areas of poor coverage.
  • a user will be confined to a particular network to which he/she subscribes so, even if there is good or acceptable coverage for one network, the same may not be true of another network. This could leave the subscriber vulnerable if he happens to subscribe to the network with the poorest coverage in the particular area in which he finds himself requiring a location service.
  • cellular auto-location systems have limited accuracy. This is not unsurprising since cellular systems never were intended for location purposes.

Abstract

L'invention concerne un système de localisation de position qui comprend une station de base (22) radio réceptrice et une pluralité de dispositifs (21) radio émetteurs/récepteurs portatifs pourvus chacun de moyens (25) permettant de déterminer la position mondiale instantanée du dispositif, et conçus pour signaler cette position à la station de base. Chaque dispositif permet de surveiller les transmissions provenant d'autres dispositifs du système et de relayer les messages d'un dispositif à un autre, ce système permettant de transmettre par relais à la station de base un message provenant d'un dispositif se situant hors de la portée de celle-ci.
