Re: Yeni Atılacak Astra 1KR Hakkında bilgisi olan varmı?
ASTRA 1KR is an all Ku-band spacecraft that will provide distribution of direct-to-home broadcast services across Europe. It is equipped with 32 active transponders, which will be reduced to 28 active transponders after the first 5 years. The satellite will be located at 19.2 degrees East longitude, replacing ASTRA 1B and Astra 1Cyukardakılerın suresı dolmus onların yerıne bu uydu
Satellite launch information
Satellite orbital information
- Launch date: 20.04.2006
- Launch vehicle: Atlas V
- Launch site: Cape Canaveral, USA
- Launch mass: 4332kg
- Satellite manufacturer: Lockheed Martin
- Orbital location: 19.2° east
- Transponder capacity: 32/28
SATELLITE LAUNCH DETAILS
The Atlas V launch will place the Lockheed Martin-built ASTRA 1KR satellite into orbit for SES ASTRA. The Atlas V will lift off from Launch Compex 41 at Cape Canaveral Air Force Station, Florida. The geosynchronous tranfer orbit mission design will use a sub-synchronous trajectory design with two Centaur burn phases. The satellite's attitude and orbital control system will perform a series of burns to achieve geosynchronous altitude, circularize the orbit and reduce inclination. The duration of the flight is one hour and 48 minutes from liftoff to spacecraft separation.
