CONT

In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers ...

CONT

The higher power of the RADARSAT-2 downlink will permit the size of the ground station antenna to be substantially smaller and subsequently more affordable. The standard RADARSAT-1 antenna is approximately 10 metres in diameter; this can be reduced down to 3 metres for RADARSAT-2. This will allow the use of portable ground stations.

OBS

downlink: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Trajet parcouru par le signal entre un satellite et la station terrestre réceptrice.

CONT

Une densité de puissance plus élevée en liaison descendante permettra l'utilisation d'antennes réceptrices beaucoup plus petites, et par conséquent moins coûteuses. Une antenne réceptrice utilisée pour RADARSAT-1 a un diamètre d'environ 10 mètres; le diamètre de l'antenne peut être réduit à 3 mètres avec RADARSAT-2. Ceci permettra aussi l'utilisation d'antennes réceptrices mobiles.

OBS

liaison descendante : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

PHR

Émetteur haute puissance en liaison descendante.
