NASA infrared satellite data sees system 96P developing tropically near Vanuatu
( NASA/Goddard Space Flight Center ) The low pressure area called System 96P in the South Pacific appears to be getting organized in infrared satellite imagery from NASA. System 96P is showing signs of strong convection and that has prompted the government of Vanuatu to issue tropical cyclone warnings today.

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.

Discover Mississippi?s Musical Roots Using Satellite Internet

Discover Mississippi?s Musical Roots Using Satellite Internet

As a Mississippi native, you should know that your state is considered by some to be the birthplace of blues, rock and roll, and even country music. Home to greats B. B. King and the King, Elvis Presley, Mississippi’s heritage is steeped in musical traditions. With that being said, you’d be crazy not to learn about the state’s musical history and visit some of the historical sites across Mississippi. However, if you don’t have the time or money, especially in this economy, there is a cheaper solution – satellite internet.

Given that Mississippi is a mostly rurally populated state, high-speed internet may not be widely accessible everywhere. In many places you are left with the sole option of a dial-up connection. Some places may not even have dial-up available. A satellite hook-up can provide internet to every nook and cranny of Mississippi, thus giving all Mississippians access to uncover and share musical traditions not just statewide, but worldwide.

Here’s how it works. Satellites orbiting Earth transmit and receive signals to and from your satellite dish. It’s the very same kind of technology that powers satellite television. The goal of satellite television is to bring television into homes where cable wires could not reach. The intent of satellite internet is the same. All you need to get started is the installation of a satellite dish to the top of your home. You will quickly see that your browsing and downloading speeds are much faster using satellite – often up to thirty times that of dial-up connections.

So, now you must be wondering how satellite technology can keep you in touch with Mississippi’s musical traditions. The ways are endless. You can purchase the music of legendary Mississippians via iTunes. You can buy hard-to-find vintage records on eBay. You can listen live to specialized Mississippi online radio stations. Or upload your own music and create your own Magnolia State station. You can participate and chat on fan sites of your favorite home-grown artists. You can read their biographies. You can watch old videos on YouTube. As you can see, the possibilities to stay connected with Mississippi’s musical roots really are endless with satellite internet.

When you have enough money and time, you can plan a trip across the state to visit all the historic musical sights. Check out the birthplaces of B. B. King, Elvis, and the great Muddy Waters. Or how about the childhood homes of some current music superstars: Lance Bass, Brandy, Jimmy Buffett, Faith Hill, LeAnn Rimes, or 3 Doors Down? Also, be sure to take a look at the newly created, government-funded Mississippi Blues Trail. Along this trail are more museums than you can count; in addition to birthplaces, archives, record stores, and much more.

No matter which part of the state you hail from or how remote it is, you too can have unlimited, always-connected access to the web thanks to satellite internet. Keep in mind that streaming radio stations online and other examples mentioned above are not possible with your dial-up connection. The Mississippi music lover in you will appreciate your decision to upgrade to satellite.

Let satellite internet providers help you get connected today. A true music-loving Mississippian can’t pass up on the great opportunities from satellite internet Mississippi.
