"You dial the user that call to be absent service division... " to user of major mobile phone, the likelihood has encountered such awkwardness.
Nevertheless, it is about to make the history!
Recently, group of Chinese spaceflight science and technology announces, our country will begin to begin to build constellation of satellite of global low course, launch first satellite of the system this year.
Whole constellation main body predicts to built 2023. At the appointed time, no matter be,still be in in mountain forest desert boundless and indistinct sea, the mobile phone can have signal.
The system builds 3 paces to take the strategy
According to CCTV press, the constellation of satellite of global low course that is about to build names for " swan goose " , as the ceaseless promotion of ability of our country spaceflight, and people rises to what Internet serves demand, future will be offerred through the satellite faster, stabler, more safe also Internet receives a service.
Zhang Hong of dean of academy of technique of vacuum of China of group of spaceflight science and technology too express, "Swan goose " construction cent of the system takes the strategy for 3 paces.
Above all, the first test satellite that is about to launch this year, will move in distance earth the orbit of 1100 kilometers, basically assume the ability of usability of resource of frequency of low course of test and verify and data transmit service;
Next, we should realize a local area network before 2020 6 stars, realize test and verify of link of local area network;
To 2023 54 stars are finished (blast off) later, we have the capacity that the whole world communicates, gather capability with global data, after waiting for 270 stars to fill, we have global broadband to be received, speech corresponds the application of 6 respects.
After the satellite finishs the group net that 3 paces walk along to work, will formal offer the high speed that does not have blind angle to get online to global user service.
In addition, piece Introduction Hongtai, compare at what at present we use ground Internet, the network that place of swan goose system provides will not accept space and district restriction, be in the place that area network cannot enclothe especially, can offer cover network service completely without blind angle.
"Did not come after satellitic Internet receives a service to gain ground, our life will be more convenient, network mode switch also can resemble double now card the mobile phone is same, relaxed freely, implementation is not had seam join. To that moment, you are taking a mobile phone not to feel what use to you is satellitic network or area network, the life quality that safeguard improves people " piece Hong Tai says.
Not only such, zhang Hong still emphasizes too, "Swan goose " the system still has global navigation to enhance a function, the north that can be our country fights navigation system to raise fixed position precision further.
Market dimensions or one billion four hundred and ten million and sixty-five thousand four hundred and eight yuan of levels
On March 7, industry and informatization ministry issued business certificate of fundamental telecommunication business to Inc. of limited company of group of Chinese spaceflight science and technology and group of Chinese satellite communications, approval China is defended inside countrywide limits business of management satellite mobile and satellite secure communication business.
According to " economic reference signs up for " report, inside course of study think generally, china is defended obtain batch of business license plate, mean satellite communications business to already had operation base in our country, the market is maturing gradually.
As system of satellite communications of new generation of prospective our country blast off and apply, market of our country satellite communications will enter fast hair exhibition period,
Be worth what carry is, report of Xinhua News Agency points out, china is defended obtain fundamental telecommunication business to manage a license, implement national space strategy to our country not only, health of market of stimulative telecommunication business, orderly development and sth resembling a net of day earth mat chasm of word of divisor of organic confluence, disappear, promote telegraphic and general service, lash-up communication and development of deepness of confluence of the army and the people have important sense,
And supporting construction of society of our country economy effectively, promote " one belt all the way " interconnection each other connects information of state of along the line to develop with collaboration, extend from " satellitic Internet + " to " net of couplet of satellitic other people + " the respect such as industrial modes of life and relation to their environment also will produce major effect.
According to introducing, china is defended already launched satellite of broadband of first tall flux of our country at succeeding in April 2017, built the business operation platform of an organic whole of heaven and earth, had wait for the capability that provides satellitic Internet to receive a service to masses consumer and civil aviaton plane, marine passenger-cargo vessel, Gao Tie, open Internet of our country satellite develops new era.
Did not come 5 years, china is defended still will launch satellite of broadband of 3 tall flux, total capacity is not less than 500 Gbps, implementation is reached to our country territory " one belt all the way " of main area enclothe completely.
Meanwhile, china defends an organization in group of spaceflight science and technology to fall took an active part in " swan goose constellation " construction, plan general at " 945 " during complete overall arrangement of constellation whole world basically.
At the appointed time, the whole world that our country will build fast track satellite and tie of low course constellation is enclothed, be in harmony of heaven and earth is connected, along with encounter receive, the day that uses rich, on the safe side base system of website sth resembling a net, safeguard of service of of all kinds news needs contented country, it is network of 5G of ground of satellitic Internet confluence and content couplet net to create capacious development vacuum.
Future tens of year " super plan "
Spaceflight career of China, start in poor. Great cause, advance ceaselessly in firewood fire according to legend.
Eastwardly red horizontal stroke of a satellite is born for nothing, return day of type satellite make one's rounds to return to the first; Carry a person to ask a day from divine boat airship, to " goddess in the moon " " the Jade Hare-the moon " month of 10 thousand lis of visit; From " north is fought " net of group of series navigation satellite moves, to hand in meeting butt joint to establish dimensional lab...
"Explore vast universe, grow spaceflight enterprise, build spaceflight power, it is us the spaceflight dream of indefatigable pursuit. " navigate person this speech is heart-stirring, put forward clearly to build the strategic goal of spaceflight powerful nation.
Science and technology of group of Chinese spaceflight science and technology appoint director Bao Weimin says, this group is being driven heavy-duty and locomotive, carry a person to enter a month, repeat use spaceflight to carry the major project such as the system and demonstrate project approving of project of test and verify.
Implementation carries a person to enter a month, need to solve locomotive difficult problem above all.
China is being begun those who be used at heavy-duty rocket 3 model the crucial technology of liquid engine tackles key problem and plan deepens argumentation, heavy-duty rocket plans to be in 2030 around " head fly " .
Zhang Bainan of total stylist of system of manned airship of academy of Chinese vacuum technique introduces, china already aimed at technology of international forward position to begin research of new generation manned airship, this airship can enter a month with Yu Zairen, "Will use with can repeating, have a variety of utility to be a feature " .
Zhao Xiaojin of assistant dean of academy of Chinese vacuum technique is in suffer when visitting, say, china is planning visit month the 4th period project, future builds moon base likely.
Want to move back and forth space, the researcher must be found new " motivation " . Liu Zhirang of 6 courtyards dean says group of science and technology of spaceflight of delegate of countrywide National People's Congress, China, they are considering to design an unit related Chinese nuclear power jointly, begin argumentation of plan of dimensional nuclear power and work of crucial technology research, sequel will form a variety of plan such as report of nuclear heat, nucleus.
According to project of Chinese manned spaceflight " 3 paces go " the strategy, strive 2020, our country exceeds 200 in course spacecraft amount, year emissive amount achieves the left and right sides 30 times, reach level of world spaceflight power basically;
To 2030, drive our country to reach the space technology target that one running water makes the same score international from 30% rise 60% , train of power of spaceflight of bound of ascend one's life experience; To 2045, build world spaceflight power in the round.
Cheer! China!
