Star 6B satellite in China Satellite Communications Corporation in July 2005 to the French Virginia Aerospace, Inc. (Thales) Order of the communications and broadcasting satellite, was in July 2007 5 in China, Xichang Satellite Launch Center Long 3 B rocket, was successfully positioned at longitude 115.5o.

1, Satellite Design Principles Satellite platform and payload optimization of advanced and mature technology and design to ensure long life and high reliability. Select France SB4000 satellite platform, the design power of 9000 ~ 10000W, design life of more than 15 years; star on the fuel, solar panels output power, has Battery And traveling wave tube Amplifiers So there is a certain margin, or back up, launch insurance and meet the needs of in-orbit lifetime.

Satellite downlink coverage in Asia and Oceania, down the equivalent isotropic radiated power in the coverage area is greater than 35dBW above, the satellite antenna configuration more vice to form a variety of beam coverage, the satellite transponder can be used flexibly to meet the user voice, data, image and multimedia transmission service needs.

2, the state of satellite technology

6B satellite in satellite design life of 15 years, the service life of 16.5 years. Satellite size 2.25m × 2m × 4.5m, satellite dry weight 1847kg, a launch weight of 4516kg, solar panels for the north and south solar wings, each wing formed by the four, the maximum output power of 10400W, currently, the normal output power of 9670W, end of life power of 8500W. On-load when two groups 92A Ni-MH batteries, 54 batteries each monomer. Track keeping accuracy of ± 0.05o, antenna pointing accuracy 0.13o, the end of satellite life reliability of 0.75.

Satellite payload design considerations application requirements, make full use of the resources of C-band, standard and extended frequency band, occupying a bandwidth of 1.6G. Configure the satellite transponder 38, a bandwidth of 36MHz, traveling wave tube amplifier power 82W, Transponder 24, prepared for the two groups of 19, communication receiver preparation for the 6 4. Polarization isolation is: China and the surrounding areas> 33dBW, other coverage area 30dBW.

For the convenience of users, configure a 1.4m satellite antenna and two 2.4m antennas, respectively, the formation of the Asia-Pacific, regional and national beam.

Satellite downlink coverage area to all of China, Mongolia, the Korean Peninsula, Japan, Russia, parts of Asia, South Asia, Southeast Asia, Central Asia, West Asia, Australia, New Zealand, covering areas EIRP (equivalent isotropic radiated power): 36 44.5dBW.

Downlink EIRP: Beijing, Shanghai, Guangzhou, Kunming, Lanzhou, connecting the central area 42dBW, the Chinese territory (except the South China Sea) 41dBW, the South China Sea 40dBW, Asia, Australia, most of 37dBW, New Zealand and Some South Pacific islands 36dBW.

SFD (saturation flux density): -70 ~ 95dBW/m2.

G / T =- 5dB / K (Asia beam).

Beacon frequency: Horizontal 4199MHz, vertical 3701MHz. Chinasat 6B

Frequency Counter Planning Map 6B satellite downlink in the satellite coverage map (3920MHz)

3, satellite operations and services

China Satcom satellites in order to ensure the healthy operation of building in the life of a satellite control stations and satellite communications control center, weather monitoring and management of satellite body and the operation of communication services.

Among the Broadway Musicals South Pacific is Supreme!

Among all the Broadway musicals, “South Pacific” has the most powerful songs and a thought provoking storyline. What happens when people fall in love with each other during a war? Do they remain under the mercy of the wrath of war? Or can they emerge as winners?

“South Pacific” has created history not only for its love story interwoven with war-time, but also for highlighting the taboo topics of racism and prejudice. Eyebrows were raised. Creators were pressurized. However, there emerged a musical story that created history and became one of the greatest musicals on Broadway.

The author of the book “Tales of the South Pacific” had to ask the creators of the musical, Hammerstein and Rodgers, to remove the song “You’ve got to be carefully taught” because it contained certain harsh comments on racism.

Last shown in 1949 at the Majestic Theatre, “South Pacific” is again ready to set the stage on fire by its blatant expression of emotions at the Vivian Beamont Theatre on April 4, 2008. It’s nearly after 6 decades that the audience will get a chance to see the marvelous work of Richard Rodgers (music composer), Oscar Hammerstein II (lyricist), and James A. Michener (original writer of the book).

In 1948, the book won Pulitzer Prize for Fiction, while in 1950, the musical won Pulitzer Prize for Drama. It’s also the only musical of its kind to win four Tony Awards!

The story is set in the backdrop of World War II. It revolves around two couples who fall in love with each other amidst war. Nellie is a nurse in the US Navy while Emile is an owner of local plantation. They both love each other. On the other hand, Lt. Joe Cable and young local Liat start loving each other. Now, the big question is: Will the two couples get a chance to live their love or will the cruel war take over them?

Among the Broadway musicals, “South Pacific” is one of the most intriguing love stories that you can ever see. The issue of racism and prejudices is handled with care and intelligence in this musical. Although the story makes you to think about certain issues, overall, it’s an entertainer.

Watch the show with your family or watch alone; watch with your friends or take your partner with you – do whatever, but watch this show! It’s a strong love story; in fact, there are two short stories blended as one.

The tickets to the Broadway musical “South Pacific” are already starting to vanish from the box office! If you don’t want to be disappointed, rush to book your tickets. There are also easier ways to get to the theatre – call a number or log online. The ticketing services will see to it that you get tickets of your choice show, even front row seats!

So, are you ready to know the realities of war? Do you want to know what happens to love when it takes place during a war? If yes, then pick your phone now and book!
