CA 2334771
A method and apparatus for determining the length of a train utilizing received signal such as a reference signal from a global positioning system or the like is disclosed. A first receiver (104) receives a signal, such as a reference signal from a global positioning system (208) or the like, from which a first position on a train may be determined. Similarly, a second receiver (110) receives a signal from which a second position on the train may be determined. A processor (210 and 228), operatively coupled to the first and second receivers, determines the lengths of the train based on the first and second positions.
L'invention concerne un procédé et un appareil servant à déterminer la longueur d'un train grâce à la réception d'un signal tel qu'un signal de référence provenant d'un système mondial de localisation ou similaire. Un premier récepteur (104) reçoit un signal tel qu'un signal de référence provenant d'un système mondial de localisation (208) ou similaire, qui permet de déterminer une première position dans un train. De façon semblable, un second récepteur (110) reçoit un signal qui permet de déterminer une seconde position dans ce train. Un processeur (210 et 228), couplé de manière fonctionnelle aux premier et second récepteurs, détermine la longueur du train sur la base des première et seconde positions.
