Globalstar satellite up and running
(Dec  17  2010)

Globalstar has announced that it has completed pre-operational testing of its first new second-generation satellite, and that the spacecraft has successfully processed its first commercial telephone call.

The new satellite is the first of six that were launched in Autumn 2010 to come online, and Globalstar says that it is now ready to fully support voice and duplex data services.

Four of the satellites are planned to be made operational up to the end of January 2011, with the remaining two expected to be deployed near the end of the first quarter of 2011.

Globalstar has also announced that it is making final preparations to accept delivery of two additional new second-generation satellites from manufacturer Thales Alenia Space, with the deliveries scheduled to take place around the turn of the year.

The second batch of six Globalstar satellites is due to be launched from the Baikonur Cosmodrome in Kazakhstan, using the Soyuz launch vehicle, similar to the company's other recent launch.

“Following successful intensive testing of the new spacecraft by our satellite operations control centre and engineering personnel, we are pleased to announce that the first Globalstar commercial call using our new second-generation satellite was processed for a customer calling in Korea and we are proceeding with testing and deployment of the remaining five satellites,” said Tony Navarra, president of global operations for Globalstar.

“(This) announcement and the anticipated deliveries of our new spacecraft for our second satellite launch represent further milestone achievements for our second-generation satellite operations.”

“Once more I applaud our highly skilled global operations employees as well as those at Thales Alenia Space, who helped make (this) possible.”

Globalstar plans to integrate its 24 new second-generation satellites with eight first-generation satellites that were launched in 2007, to form a 32 satellite constellation.

As each new Globalstar satellite becomes operational, the company says that service availability and reliability will improve for users of its voice and duplex data services.

The new constellation and ground network, expected to be installed by 2012, is designed to provide increased data speeds of up to 256 kbps in an internet protocol multimedia subsystem (IMS) configuration

 

글로벌스타2세대 위성이 운영테스트를 완료하고, 위성과 최초로 음성전화 통화를 확인했다.

새로운 글로벌스타 위성은 2010년 10월에 발사가 완료 되었고, 완전한 음성과 양방향데이터통신도 서비스를 지원하기 위한 준비가 되었다.

 

또한, 2번째 위성발사에 대한 위성도 제작이 되어 발사체가 있는 소유즈에 전달 되었다.

 

새로운 위성의 신호 교신이 "한국"에서 최초로 2세대 위성을 이용하여 처리가 되어 매우 기쁘다.

 

앞으로 새로운 2세대 위성이 발사 성공을 하여 기존 운영하는 위성과 통합되어 운영할 계획이다.

그렇게 진행되면, 글로벌스타는 서비스의 가용성 및 안정성은 차츰 음성 및 데이터 서비스의 사용자들이 개선된것을 느낄것이다.

2012년이 되면, 256kbps의 속도의 데이터 속도로 저궤도 위성서비스를 만족하게 될것이다.

 

이상.
