Problématique et introduction
à la solution
12
Problématique
 Le signal variable formé par la modulation d’amplitude dans l’espace pour le
VOR C est très sensible aux multi trajets, ce qui implique des erreurs VOR
trop importante dans un milieu entouré par les obstacles et rends le VOR C
quasiment inexploitable
13
Introduction à la solution :
Pour rester compatible avec les récepteurs VOR des
avions, l’idée vient d’inverser les modulations des
signaux:
 Rayonner le signal référence en modulation AM
 Rayonner le signal variable en modulation FM
C’est le principe sue lequel a été créé le système VOR-D
qui va remplacer l’ancien module de VOR-C.
