Title
(EN) TELEMATICS DEVICE COMPRISING THE COMBINATION OF A CELLULAR TELEPHONE AND AN ELECTRONIC NAVIGATION APPARATUS
(FR) DISPOSITIF TELEMATIQUE
Abstract
(EN)
A telematics device comprises the combination of a cellular telephone and an electronic navigation apparatus. The cellular telephone includes a reference oscillator (122) which is also coupled to the electronic navigation apparatus, thereby reducing the cost of the telematics device by avoiding the need for two reference oscillators and also improving the performance of the device by reducing the time to first fix when the electronic navigation apparatus is switched on as the reference oscillator is controlled to a tighter specification than is normal for a stand-alone electronic navigation apparatus.
(FR)
L'invention concerne un dispositif télématique servant à la fois de téléphone cellulaire et d'appareil de navigation électronique. En tant que téléphone cellulaire, ce dispositif comprend un oscillateur de référence (122) couplé audit appareil de navigation électronique: il n'est plus donc nécessaire d'utiliser deux oscillateurs de référence, ce qui permet de réduire le coût de ce dispositif télématique. L'efficacité de ce dispositif est par ailleurs améliorée, étant donné que le temps de fixation initiale est réduit, lorsque l'on allume ledit appareil de navigation électronique pour la première fois, l'oscillateur de référence du dispositif de cette invention répondant par ailleurs à des normes plus strictes que ceux des appareils de navigation électronique autonomes traditionnels.
