CONT

One of the intended missions of the DRAC system is to immediately detect all presence or advancing infantry units or vehicles at a particular location or within a specific corridor in the command zone of the reconnaissance units, without having to deploy any ground sensors. Each system consists of two fixed-wing aerial vehicles from the Tracker series, interchangeable gyro-stabilised visible-spectrum and infrared payloads, a data link and a portable, multifunction, ruggedised ground station. The latter in turn comprises two sets of functions : for mission preparation and control and for payload operation respectively. The complete equipment is packed in a rucksack that can be easily transported and deployed by two men. This feature makes DRAC particularly suitable for use by paratroopers.

CONT

Un système DRAC se compose de deux vecteurs aériens, de deux consoles de suivi et d'exploitation de mission, de deux capteurs jour et un de nuit. Il est mis en œuvre par une équipe de deux hommes. Le vol et l'atterrissage se font en mode autonome (aucune expérience d'aéromodélisme requise). Faciles d'emploi et de mise en œuvre, de masse et d'encombrement réduits, ils permettent d'envisager la réalisation de missions avec une grande souplesse et des cycles de coordination et de décision courts.

  • Surveillance, Detection and Reconnaissance (Military)
CONT

Serving as a means of aerial reconnaissance and surveillance rather like "an extended pair of binoculars", DRAC enables an operator to gather, display and process real-time images at a distance of up to 10 kilometres, by day or by night. One of the intended missions of the DRAC system is to immediately detect all presence or advancing infantry units or vehicles at a particular location or within a specific corridor in the command zone of the reconnaissance units, without having to deploy any ground sensors. Each system consists of two fixed-wing aerial vehicles from the Tracker series, interchangeable gyro-stabilised visible-spectrum and infrared payloads, a data link and a portable, multifunction, ruggedised ground station. The latter in turn comprises two sets of functions : for mission preparation and control and for payload operation respectively. The complete equipment is packed in a rucksack that can be easily transported and deployed by two men. This feature makes DRAC particularly suitable for use by paratroopers. The responsibility for developing and manufacturing the DRAC systems has been conferred on EADS, as overall prime contractor, working in partnership with SurveyCopter.

[...] EADS a commencé, début juin, la livraison à la DGA des 25 systèmes Drac (Drones de renseignements au contact), de petits drones portables par le fantassin et destinés à voir «au-delà de la colline» avec une portée de 10 km. [...] Le Drac fonctionne sous protocole IP (Internet Protocol), ce qui permettra de mettre en réseau avec d'autres systèmes présents en unité et de l'intégrer sur SIC (Système d'information et de commandement). Et, outre une antenne omnidirectionnelle pour le décollage, il dispose [...] d'une antenne monodirectionnelle, pour plus de discrétion en vol.

Record 4 2006-10-24

English

Subject field(s)
  • Satellite Telecommunications
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).

PHR

High-power downlink transmitter.

Key term(s)
  • down link
  • down-link

French

Domaine(s)
  • Télécommunications par satellite
DEF

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.
