With the termination of SA [selective availability], ionospheric delay becomes the largest contributor to the GPS error budget(Shaw et al., 2000). As the ionosphere is a dispersive medium, it causes a delay to the GPS signal that is frequency dependent. Therefore, using a dual frequency receiver, we can combine the L1 and L2 measurements to generate the so-called ionosphere-free linear combination, which removes the ionospheric error. 4, record 5, English, - dual%2Dfrequency%20receiver

Depuis la levée de l'accès sélectif (A/S), c'est le retard ionosphérique qui contribue le plus au bilan des erreurs GPS (Shaw et alii, 2000). Comme l'ionosphère est un milieu dispersif, le signal GPS y subit un retard qui est fonction de la fréquence. Par conséquent, si on utilise un récepteur double fréquence, on peut combiner les mesures aux fréquences L1 et L2 pour générer la combinaison dite linéaire sans ionosphère, c'est-à-dire, exempte de l'erreur ionosphérique. 2, record 5, French, - r%C3%A9cepteur%20bifr%C3%A9quence

All components have been miniaturised in a device incorporating AM/FM RDS radio, CD audio player and navigator with a large graphic display.

For static positioning, the reconstructed carrier phase is sampled at epochs determined by a clock in the receiver. The reconstructed carrier phase changes according to the continuously integrated Doppler shift of the incoming signal, biased by the integral of the frequency offset between the satellite and receiver reference oscillators. The reconstructed carrier phase can be related to the satellite-to-receiver range, once the initial range(or phase ambiguity) has been determined. A change in the satellite-to-receiver range of one wavelength of the GPS carrier(19 cm for L1) will result in a one-cycle change in the phase of the reconstructed carrier. 1, record 11, English, - reconstructed%20carrier%20phase

La phase reconstituée de la porteuse varie en fonction du décalage Doppler, intégré de manière ininterrompue, modifié par l'intégrale du décalage de fréquence entre les oscillateurs de référence du récepteur et du satellite. La phase reconstituée de la porteuse peut être mise en relation avec la distance satellite-récepteur une fois la distance initiale (ambiguïté de phase) déterminée. Une modification de la distance satellite-récepteur égale à une longueur d'onde de la porteuse du GPS (19 cm pour L1) résulte en une modification égale à un cycle de la phase reconstituée de la porteuse. 1, record 11, French, - phase%20reconstitu%C3%A9e%20de%20la%20porteuse

GPS measurements can be differentiated between receivers, satellites, and epochs. Although many combinations are possible, the present convention for differential processing of GPS phase measurements is to take differences between receivers(single difference), then between satellites(double difference), then between measurement epochs(tripe difference). A single difference measurement between receivers is the instantaneous difference in phase of the signal from the same satellite, measured by two receivers simultaneously. A double difference measurement is obtained by differentiating the single difference for one satellite with respect to the corresponding single difference for a chosen reference satellite. A tripe difference measurement is the difference between a double difference at one epoch of time and the same double difference at the previous epoch of time. 1, record 15, English, - difference%20processing

Des différences entre mesures GPS peuvent être calculées pour différents récepteurs, différents satellites ou différentes époques. Bien qu'un grand nombre de combinaisons soient possibles, il est actuellement convenu d'adopter les différences entre récepteurs (différence simple) pour le traitement différentiel des mesures de phase effectuées au moyen du GPS plutôt que les différences entre satellites (double différences) ou les différences entre des époques de mesure (triple différence). Une mesure par différence simple entre récepteurs est la différence instantanée de phase du signal d'un même satellite telle que mesurée simultanément au moyen de deux récepteurs. Une mesure par double différences est obtenue en soustrayant la différence simple pour un satellite de la différence simple correspondante pour un satellite de référence. Une mesure par triple différences est la différence entre une mesure par double différences à une époque donnée et la même mesure par double différences à une époque antérieure. 1, record 15, French, - traitement%20des%20diff%C3%A9rences
