Wenchang Satellite Launch Center
2. Located in Longlou Town, Wenchang City, Hainan Province, China, Wenchang space launch site is the first open coastal space launch base in China and one of the few low latitude launch sites in the world
the launch site can launch Long March 5 Series rockets and Long March 7 launch vehicles, and mainly undertake the launch tasks of geosynchronous orbit satellites, high mass polar orbit satellites, large tonnage space station and deep space exploration satellites
extended data:
architectural layout
Wenchang space launch site is mainly composed of launch site area, supporting measurement and control station and other areas, including launch area, technology area, test cooperation area, technical service support system and so on. The total area of the project is about 18531 mu
historical evolution
the predecessor of Wenchang space launch site was China's test base for launching suborbital rockets, and then approved by the State Council and the Central Military Commission to build China's first coastal launch base there
3. In a corner of a watermelon field, there is a humble stone pile, which is written on all sides as "the first launch station 2K1". This point is the central position of the future launch center that the researchers have measured many times over the past few years. That is to say, the launch tower of the future space city is most likely to rise flat here. Walking along the southeast of the launch tower for 10 minutes is a winding coastline. According to reports, the location of the launch tower to the sea, in fact, the straight-line distance is only 800 meters, in the future, the rocket will be over the sea immediately after liftoff. Therefore, the containment of ground residents' safety factors will be greatly reced
4. Wenchang satellite launch center generally refers to China's Wenchang space launch site. It is located in Longlou Town, Wenchang City, Hainan Province, China. The location of the launch site is about 19 degrees north latitude. Wenchang space launch site in China is the first open coastal space launch base in China and one of the few low latitude launch sites in the world
The construction of Wenchang space launch site started in September 2009, which is composed of five systems, including test launch, measurement control, communication, meteorology and technical service support. It mainly undertakes the launch tasks of geosynchronous orbit satellite, mass polar orbit satellite, large tonnage space station, cargo spacecraft and deep space probe. The launch center can launch Long March 5 Series rockets and Long March 7 carrier rockets
in January 2015, the Long March 7 carrier rocket has arrived at Wenchang space launch site, which is the first appearance of the Long March 7 carrier rocket and Wenchang launch system

5. Everything is subject to the official announcement. Any so-called grapevine news is unreliable. Wenchang is the first launch and will definitely announce the launch time. At that time, the public can watch the satellite launch within the specified range.
6. 1 B2C virtual card 1. Payment mode B2C enterprises can provide users with all kinds of Internet value-added services, such as Shanda's online games, Tencent's various virtual procts based on im (instant messaging), and can also sell users all kinds of physical goods, such as excellent audio-visual books. At the present stage, Internet value-added service providers have issued all kinds of virtual cards, while pure B2C commodity sales enterprises have not. After purchasing the recharge cards of these companies through various channels, users will get a series of unique corresponding numbers (serial codes), and use these numbers to recharge the corresponding virtual cards. After the recharge, the virtual card account can purchase the procts of these companies online. The commonness of this kind of virtual card is mainly as follows: · it is mainly used for micro payment. Because the price of virtual procts is generally less than 50 yuan, such as Tencent's QQ prop price is 1 ~ 5 yuan· The frequency of virtual card recharge is high. For example, the face value of Shanda game point card is 10, 20, 30 yuan. If the average monthly cost of each game player is 60 yuan, there will be at least two purchases per month· Virtual procts are highly standardized and digital procts, so they are very suitable for online transactions. 2. Recharge channels at present, the recharge channels of B2C virtual cards are mainly divided into two categories: the first is the traditional way, such as convenience stores, newsstands and other stores to buy physical cards to recharge; The second is electronic channels, such as mobile phone, fixed line telephone, Internet, etc. Taking Tencent's QQ coin virtual card as an example, there are five ways to purchase it: (1) recharge the QQ coin card. Q-coin cards are sold in the form of physical cards. There are three face values of physical cards: 10 yuan, 15 yuan and 30 yuan, which can be purchased in convenience stores, newspaper kiosks and software stores 2) Recharge through TenPay. TenPay is Tencent's virtual account, which can be recharged by bank card (currently including eight banks including instry, construction and agriculture), which is equivalent to purchasing virtual card 3) Broadband recharge. China Telecom's Internet star Vnet (ADSL broadband users) and China Netcom's ADSL broadband users can recharge q-coin through their own ADSL accounts, and the fees are dected from the monthly bills. At present, the areas opened are limited 4) Voice phone recharge. Use fixed line telephone or PHS to dial the hotline 16885885 and press the prompt tone to recharge the Q coin into the personal account. The fee will be dected from the monthly phone bill 5) Other recharge methods. For example, Shanghai users can buy a telecom card to recharge their QQ account, and Shanghai Unicom users can get QQ coins by dialing 1015908826 on their mobile phones, and the fees will be dected from their mobile phone bills 2 At present, there is only one way to recharge C2C virtual card, that is, to recharge the virtual card through the bank's online banking. For example, Alipay has been connected with ICBC, such as ICBC, ABC and other nine banks. EBay's PayPal supports 12 bank cards. 1、 With the development of e-commerce, more and more enterprises enter the virtual card market. At present, there are more than 400 virtual card issuers in the domestic market. In terms of C2C, Tencent, the largest im (instant messaging) Company in China, announced the launch of paipai.com in March 2006 and officially entered the virtual card market. In terms of B2C, the online game virtual card market is developing rapidly. According to the survey of iResearch, the domestic online game market exceeded 6 billion yuan in 2005, an increase of 51% over 2004. China's largest search engine network, also launched its own virtual card network coin at the end of 2005. It is worth mentioning that in addition to the payment function of ordinary virtual cards, network currency also has the function of exchanging with other virtual cards. At present, it has completed one-way docking with 24 kinds of virtual cards, and 24 kinds of virtual cards can be purchased online. With the increase of participating companies, the market competition becomes very fierce. At present, Alipay and paypal are the largest share of C2C virtual card market. According to the 2005 China e-commerce research report released by the Chinese Academy of Social Sciences, Alipay has replaced 72.2% with its market share, becoming a new leader in China's C2C market. In order to gain an advantage in the competition, virtual card companies began to focus on other emerging payment fields. PayPal launched mobile payment in Canada, and eBay is also cooperating with Tom online to launch a new WAP mobile shopping website. The continuous development of e-commerce market promotes the development and change of virtual card market. The function of virtual card will be stronger and stronger, and its application scope will be wider and wider. On the whole, the virtual card market will present the following four development trends: (1) the number of virtual card issuers is graally increasing. With the deepening of e-commerce, the demand for online payment is also expanding, prompting more and more companies to issue virtual cards, such as travel agencies, tax bureaus, insurance companies and even banks themselves. Tourism is a typical cross space instry, which has a great demand for electronic payment and settlement. At present, Ctrip and elong, the two largest tourism websites in China, provide virtual accounts for their customers. Although the current utilization rate is not very high, the market prospect is broad. In the field of directional payment, virtual cards are also playing an increasingly important role. In order to facilitate taxpayers to pay taxes and policy holders to pay premiums, tax bureaus and insurance companies have begun to provide virtual cards on the Internet. China Post has also launched the nethuitong virtual card business. By purchasing the nethuitong virtual card issued by China Post, consumers can directly consume on the websites of nethuitong franchisees and transfer accounts to other nethuitong customers. I believe that with the further development of e-commerce, more and more companies will issue virtual cards 2 The integration of B2C virtual card and C2C virtual card with the continuous integration of B2C business and C2C business in e-commerce, B2C virtual card and C2C virtual card are infiltrating each other. In May 2006, Taobao launched "Taobao Mall" and officially entered the B2C field. EBay also has a similar expansion trend. Tencent's TenPay account has realized the common use of internal B2C and C2C fields. The increasing integration of B2C and C2C in business will inevitably lead to the expansion of the function and application scope of virtual card. In the future, more and more virtual cards can be used in both B2C and C2C fields 3 It is the development trend that the virtual cards of different companies exchange with each other. At present, there are many kinds of virtual cards. Due to the conflict of interest between the virtual card issuers, the virtual cards cannot be used universally, which brings inconvenience to users. Based on the one-way exchange of 24 kinds of virtual cards, if other virtual card issuers can be convinced to exchange with the network currency, the network currency is likely to become the general
virtual currency of network micro payment 4 More payment modes will be extended based on virtual card. When the Internet payment business is stable, virtual card issuers may consider entering other payment fields. In April 2006, PayPal launched a mobile payment solution based on PayPal account in the United States and Canada. Users bind their mobile phones to PayPal accounts. When businesses that support PayPal mobile payment shop, they only need to send the number on the goods to mobile operators by SMS, and mobile operators send the information to PayPal Mobile gateway, and then dect the money in PayPal, SMS notification businesses and customers to complete the transaction. This PayPal mobile payment mode is completed by paypal and mobile operators, without the participation of banks or other card organizations. At present, because the domestic virtual card issuers are not strong enough, this mode has not appeared in China. Once the market is mature, this kind of business may also be carried out in China. 2、 The relationship between virtual card issuers and the existing banking system (1) the cooperative relationship between virtual card issuers and banks in the Internet payment business, banks and third-party payment gateway are interdependent and complementary. One end of the third-party payment gateway is connected with the network merchant, and the other end is connected with the bank gateway. On the one hand, for banks, the third-party payment gateway manages a large number of small Internet merchants for them, so that banks can focus more on their core business and rece the burden of banks. Through the payment channels provided by banks, the third-party payment institutions can develop new value-added services and bring greater benefits to banks. On the other hand, the bank card provides the channel for the virtual card to recharge and withdraw cash. All the businesses of the virtual card are built on this basis, and the development of the virtual card is inseparable from the support of the bank card 2 There is competition between virtual card issuers and banks in the field of Internet micropayment. With the development of online payment business, there is inevitable competition between bank cards and virtual cards. For example, in the connection mode of large Internet merchants, when the gateway of the bank is not very strong, large merchants are connected to the bank gateway through the third-party payment institutions. Now the gateway of the bank is strong, and they want to connect large merchants directly to their own gateway. On the other hand, the open virtual card will also divert part of the transaction volume of online banking. However, with the maturity of the market and the further clarification of the responsibilities and positioning of all parties, the intensity of this competition will also tend to ease
