Definitions

  • the position is usually calculated by targeting the available transmitters (satellites or radio transmitters) from a receiving device.
  • transmitters tellites or radio transmitters
  • When moving through an area there may be dead spots, so that network reception is not possible.
  • the same problem arises when moving within cities, for example where there is often a lack of visual contact with the satellites when the object moves in urban canyons.
  • the US satellites only publish a certain degree of accuracy in the GPS system.
  • automobiles with GPS systems can use the coordinates calculated using the satellites and other vehicle information, for example the distance traveled after the odometer reading or the digitized data of an electronic map, are compared.
  • Position data receiver sent out In particular, this method enables the position data receiver sends an authorization signal to query the position data and that this authorization signal is checked by the position data provider before sending the position data. In this way it can be ensured, for example, that only authorized position data receivers receive the signal.
  • An authorization to receive the position data can, for example, be linked to the payment of a fee for the use of the system.
  • FIG. 2 shows a schematic illustration of a position detection system with a plurality of position data transmitters distributed in a city on different striking buildings and a mobile position data receiver.

Abstract

L'invention concerne un procédé de détection de la position d'un objet. A cet effet, une pluralité de transmetteurs de données de position (1) sont positionnés en différents emplacements (5, 6, 7). Ces transmetteurs de données de position (1) émettent chacun leurs données de position dans un domaine d'émission distinct, étroitement délimité dans l'espace. Il est prévu au voisinage de l'objet un récepteur mobile de données de position de faible portée (3) qui, lors de l'entrée dans la zone d'émission (2) d'un transmetteur de données de position (1), reçoit automatiquement les données de position émises dudit transmetteur de données de position (1) et poursuit leur traitement et/ou procède à leur affichage.
