English

Subject field(s)
  • Radio Transmission and Reception

DEF

A receiver which is capable of tracking both L1 and L2 GPS carrier frequencies.

CONT

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.

DEF

Récepteur permettant de capter à la fois les fréquences porteuses L1 et L2 du GPS.

CONT

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.

Subject field(s)
  • Electrical Power Supply
  • Radar, Radio Guidance and Goniometry
CONT

The news antenna is made up of 25 stacked double rows of helical diode phase-shifters, employing a so-called "corporate" feed method, rather than end-feed, which makes the system non-frequency dispersive in azimuth and compatible with true random frequency dispersion...
