Abstract
(DE)
Die Erfindung betrifft ein bodenbasiertes Ortungssystem zur Ermittlung einer Ortsposition eines beweglichen Objektes (1) mit einer Mehrzahl von ortsfesten Bodenstationen (2a - 2c), die jeweils eine Sende- und/oder Empfangseinheit (3a - 3c) aufweisen, und mit mindestens einer an dem Objekt (1) angeordneten Objekt festen Sende- und/oder Empfangseinheit (5), wobei die Sendeeinheiten zum Senden von Positionssignalen und die Empfangseinheiten zum Empfangen der von den Sendeeinheiten gesendeten Positionssignale eingerichtete sind und das bodenbasierte Ortungssystems wenigstens eine mit zumindest einem Teil der Sende- und/oder Empfangseinheiten (3a - 3c, 5) kommunizierend verbundenen Positionsermittlungseinheit (4, 6) aufweist, die zum Ermitteln von Entfernungen zwischen den ortsfesten Sende- und/oder Empfangseinheiten (3a - 3c) der Bodenstationen (2a - 2c) und der mindestens einen objektfesten Sende- und/oder Empfangseinheit (5) des Objektes (1) zur Ermittlung zumindest eines Empfangswinkels der empfangenen Positionssignale an der jeweiligen Empfangseinheit und zur Ermittlung einer Relativgeschwindigkeit zwischen mindestens einer der ortsfesten Sende- und/oder Empfangseinheiten (3a - 3c) der Bodenstationen (2a - 2c) und der mindestens einen objektfesten Sende- und/oder Empfangseinheit (5) des Objektes (1) in Abhängigkeit von den Positionssignalen, die von den ortsfesten Sendeeinheiten gesendet und von der mindestens einen objektfesten Empfangseinheit empfangen wurden, und/oder die von der mindestens einen objektfesten Sendeeinheit gesendet und von den ortsfesten Empfangseinheiten empfangen wurden, und die zur Ermittlung der Ortsposition der mindestens einen objektfesten Sende- und/oder Empfangseinheit (5) in Abhängigkeit von den ermittelten Entfernungen, zumindest einem der Empfangswinkel und zumindest einer der ermittelten Relativgeschwindigkeiten eingerichtet ist.
(EN)
The invention relates to a ground-based positioning system for determining a location of a mobile object (1), comprising a plurality of fixed ground stations (2a - 2c) respectively comprising a transmitting and/or receiving unit (3a - 3c), and at least one transmitting and/or receiving unit (5) that is arranged on the object, the transmitting units being set up to transmit position signals and the receiving units being set up to receive the position signals transmitted by the transmitting units. The ground-based positioning system comprises at least one position determination unit (4, 6) connected communicatively to at least some of the transmitting and/or receiving units (3a - 3c, 5), said position determination unit (4, 6) being set up to determine distances between the fixed transmitting and/or receiving units (3a - 3c) of the ground stations (2a - 2c) and the at least one transmitting and/or receiving unit (5) arranged on the object (1), for determining at least one receiving angle of the received position signals on the respective receiving unit and for determining a relative speed between at least one of the fixed transmitting and/or receiving units (3a-3c) of the ground stations (2a - 2c) and the at least one transmitting and/or receiving unit (5) arranged on the object (1), according to the position signals sent by the fixed transmitting units and received by the at least one receiving unit arranged on the object, and/or sent by the at least one transmitting unit arranged on the object and received by the fixed receiving units, and for determining the location of the at least one transmitting and/or receiving unit (5) arranged on the object, according to the determined distances, at least one of the receiving angles and at least one of the determined relative speeds.

L'invention concerne un système de localisation basé au sol servant à déterminer la position géographique d'un objet se déplaçant (1), comportant une pluralité de stations au sol (2a - 2c) fixes, qui comprennent chacune une unité émettrice et/ou réceptrice (3a - 3c), et au moins une unité émettrice et/ou réceptrice (5) située sur l'objet (1) fixe. Les unités émettrices sont conçues pour émettre des signaux de position et les unités réceptrices sont conçues pour recevoir les signaux de position envoyés par les unités émettrices, et le système de localisation basé au sol comporte au moins une unité de détermination de position (4, 6) en liaison de communication avec au moins une partie des unités émettrices et/ou réceptrices (3a - 3c, 5). Ladite unité de détermination de position (4, 6) est conçue pour déterminer la distance séparant les unités émettrices ou réceptrices (3a - 3c) fixes des stations au sol (2a - 2c), et l'unité émettrice et/ou réceptrice (5) de l'objet (1) située sur l'objet, afin de déterminer au moins un angle de réception des signaux de position reçus par l'unité de réception concernée et pour déterminer une vitesse relative entre au moins une des unités émettrices ou réceptrices (3a - 3c) fixes des stations au sol (2a - 2c) et l'unité émettrice et/ou réceptrice (5) de l'objet (1) en fonction des signaux de position envoyés par les unités émettrices au sol fixes et reçus par l'unité réceptrice (5) située sur l'objet, et/ou envoyés par l'unité émettrice située sur l'objet et reçus par les unités réceptrices au sol fixes, et pour déterminer la position géographique de l'unité réceptrice et/ou émettrice (5) située sur l'objet en fonction des distances déterminées, d'au moins un des angles de réception, et d'au moins une des vitesses relatives déterminées.
