Title (EN) POSITION FINDING
(FR) LOCALISATION
Abstract: front page image
(EN)A locator (100) receives signals from at least one beacon (110, 112 and 114). At least one beacon has a barometer (122, 124 and 126) for measuring local air pressure. The air pressure information is transmitted by the beacons with the position finding signals. The locator (100) uses the local air pressure information to calibrate its barometer (120). The barometer (120) may be used to measure the altitude of the locator (100).
(FR)La présente invention concerne une radiobalise (100) qui reçoit des signaux d'au moins une balise émetteur (110, 112 et 114). Au moins une balise possède un baromètre (122, 124 et 126) de façon à mesurer la pression atmosphérique locale. Cette information est émise par les balises avec les signaux de localisation. La radiobalise (100) utilise cette information relative à la pression atmosphérique locale pour étalonner son baromètre (120). Ce baromètre (120) peut être utilisé pour mesurer l'altitude de la radiobalise (100).
