ViaSat 1宽带商业通讯卫星，Proton-M/Briz-M ，10月19日 ...

测试中的ViaSat 1


ViaSat 1的用户终端

  卫星电话我知道，  但卫星宽带还是第一次听说

2001年用过卫星上网，在房山的一个别墅区里，反正经常断网，不稳定。也不知道是谁提供的服务器。

卫星上网？网费咋算呢？

发射到近地点多高的轨道？

6.7吨，好重啊，现在中国还发射不了，等有了长征5可以一次发射2颗

6.7吨，好重啊，现在中国还发射不了，等有了长征5可以一次发射2颗

比较重哎。  卫星直接上网很牛X。

质子M是9月20号复飞，这才一个月，就第三次发射了……

天宫一号是TG吹上去的？

这个是地球同步轨道。天宫是近地轨道。

Ka段啊，100Gbps！羡慕嫉妒恨啦。。。

不会是直接用卫星连单用户吧？！

就是的，终端有家用型，和卫星电视差不多。

好像是星网通公司，９０００的初装费，３Ｍ带宽，一个月６００服务费。当时的卫星上网上行和下行是分开的，上行是靠你用56k猫拔号，下行用卫星发到你的锅上，只要你的上行，也就是拔号很稳定的话，它的卫星下行是十分稳定的.......


你要知道，在当时大家都只有56k猫，也ISDN都没有的情况下，3M带宽已经是惊为天人了..................

不过当时２０００年底０１年初成都有些小区有长城宽带了，直接１０Ｍ到户，用起来爽歪了......

好强的带宽呀！

那个用户终端接收器看上去很小啊

会不会被解密？ 就像现在的山寨锅一样

发射成功， 等分离。

A Proton-M carrier rocket carrying the U.S. ViaSat-1 communications satellite was launched from the Baikonur Space Center in Kazakhstan, Russia's Roscosmos space agency said on Wednesday.
"The Proton-M rocket was launched according to schedule. The satellite will separate from the carrier rocket on Thursday at 7:48 a.m. Moscow time [03:48 GMT]," Roscosmos said.
ViaSat in January said the satellite launch would be delayed for several months due to a fault during a test on the satellite. The launch was originally scheduled for mid-May.
ViaSat-1 weighs six tons and should operate for 15 years at a geostationary orbit.

36000km高空，一个数据传输需要延时(2*3.6)/30≈0.25s。

我国的同步卫星技术已处于世界领先位置。1990年，我国“长征”3号火箭首次发射美国休斯公司的“亚洲”1号通信卫星，使卫星的入轨精度居该公司自己生产、发射的32颗同步卫星之首，因而震惊了世界。

现在最重的GEO卫星是谁家的？

差不多就是这个的重量了。

好像还没有7吨以上的。LS-1300平台星最重的大致如此。

质子事故后，貌似特意调整了发射顺序，把自家的一颗Garpun N1军用星作为复飞后的首射，把一颗相对较轻的QueszSat作为第二射，把这个ViaSat作为第三射。而在质子事故前，ViaSat本是排在下一发的。

质子今年后面还有两颗商业星，分别是SES 4（一颗高容量的LS-1300）和AsiaSat 5（一颗中等容量的LS-1300），另有几次原定今年的商业发射挪到明年了。

BAIKONUR COSMODROME, Kazakhstan--(BUSINESS WIRE)-- International Launch Services (ILS), a leading launch services provider for the global commercial satellite industry, successfully carried the ViaSat-1 satellite into orbit today on an ILS Proton for ViaSat, Inc. of Carlsbad, California.

The ILS Proton Breeze M launched from Pad 39 at the Cosmodrome at 12:48 a.m. today local time (2:48 p.m. EST, 18:48 GMT on October 19). After a 9 hour, 12-minute mission, the Breeze M successfully released the ViaSat-1 satellite into geostationary transfer orbit.

This was the 369th launch for Proton since its inaugural flight in 1965, and the 68th ILS Proton launch overall. The Proton Breeze M launch vehicle was developed and built by Khrunichev Research and Production Space Center of Moscow, one of the pillars of the Russian space industry and the majority shareholder in ILS.

ViaSat-1, weighing over 6.7 metric tons, is the highest throughput satellite ever built, with a total capacity in excess of 140 Gbps, more than all satellites covering North America. The all Ka-band satellite will be positioned at 115.1 degrees West longitude with an expected service lifetime of 15 years or more. ViaSat-1 was built on Space Systems/Loral’s space-proven 1300 platform with 72 spot beams; 63 in the U.S. and nine over Canada. The Canadian beams are owned by satellite operator Telesat and will be used for the Xplornet broadband service to consumers in rural Canada. The satellite is designed to deliver service for 15 years or more.

ILS President Frank McKenna said, “It is extremely rewarding to be entrusted to launch our customers’ satellites. With this successful launch on ILS Proton, we are able to support ViaSat’s innovative plan to enhance and expand high-speed broadband services with the most powerful all Ka-band satellite in the world. On behalf of ILS and Khrunichev, we congratulate ViaSat on this milestone achievement and thank the teams of ILS, Khrunichev, ViaSat and Space Systems/Loral for a job well done.”

“The successful ILS Proton launch of ViaSat-1 is a crucial part of our growth strategy to allow customers to be connected anywhere at any time and at higher speeds. This much anticipated launch is an integral step in paving the way for more affordable and better quality bandwidth to meet consumer’s increasing demands. We applaud the teams at ILS, Khrunichev and Space System’s Loral who worked tirelessly to ensure a flawless mission and launch,” said ViaSat-1 CEO, Mark Dankberg.

俄新网RUSNEWS.CN莫斯科10月20日电 俄罗斯航天署人士20日向俄新社表示，美国ViaSat-1通讯卫星与19日从拜科努尔航天发射场发射的俄罗斯"质子-M"运载火箭分离。

他说："卫星与运载火箭在预定时间正常分离。"

俄罗斯国家赫鲁尼切夫航天科研生产中心是"质子-M"运载火箭和"微风-M"助推器的研发者。

火箭和卫星都很厉害

鸟语看不懂。火箭直达？

typically in the download range of 8-12Mbps and at a price of around $50 a month.

蛮贵的……

Prior to Viasat-1, the most powerful commercial telecoms satellite in orbit was Eutelsat's Ka-Sat with a total throughput of some 70 Gbps. Online since May, it is serving European consumer broadband markets.

一型运载火箭的LEO运载能力和GTO运载能力是不同的两个数字。后者比前者小得多。

我是问发射这个卫星的火箭是直达GTO？？还是变轨

质子今年真不容易.祝贺发射成功~!

GTO就是转移轨道啊。直送GEO这种不划算的事情谁做？这是商业发射啦。就是说一型运载火箭的LEO运载能力和GTO运载能力是不一样的啊。

从LEO不能变轨到GEO？

只要卫星燃料和推力足够，想去哪里都可以。明明可以用火箭上面级送入轨，为什么消耗卫星的燃料（寿命）呢？

LEO一般指2000km以下的近地轨道，而GTO是远地点约36000km的椭圆轨道。
