China Business Wholesale Wholesale merchandise, with the resulting economic development. Specializes in commodity trading business activities. Retail symmetry. Commodity circulation is an indispensable link. Usually there are two cases: ① commercial enterprises will be sold to other commercial quantities of goods for resale business. ② commercial enterprises will be used for further processing of the production supplied to manufacturers.
Goods china products and the development of commodity exchange, increase the amount of the commodity purchase and sale, distribution extended, between producers, between producers and retailers, direct exchange of commodities, often difficult or inconvenient, so to have a special direct purchases of commodities producers, and then sub-sold to other producers or retailers in the wholesale business, the business sector with the internal division of labor between the wholesale and retail. Wholesale business, wholesale business to business generally, each approved the sale of large quantities of goods in accordance with the wholesale price. china wholesale goods, wholesale prices are lower than retail prices, that there are wholesale and retail price difference, the difference is spent by the flow of retail business costs, taxes and profits composition. Wholesale and retail business is the production of intermediate links between. Through commercial wholesale activities to the social product into circulation from production areas, play areas and the mobilization of organizations the role of commodity circulation between. Storage of goods can also play a "reservoir" effect, commodity supply and demand balance. Visit TradeTang.com.

Relative first-generation analogue phones (1G) and second-generation GSM, TDMA digital mobile phones, etc. (2G), 3G communication the name of the range, the ITU provides wholesale cell phone as "IMT-2000" (International Mobile Telephone 2000) standard, European telecom giants call him "UMTS" Universal Mobile Telecommunications System. At present, the international 3G mobile phone (3G handsets) has three kinds of standard criteria: the European WCDMA standard, the CDMA2000 standard, and the United States by the Chinese scientists proposed TD-SCDMA standard. Now "3G communications," is about to become the mantra of the mouth, the so-called 3G wholesale phones, the fact that it's all called the 3rd Generation, china wholesale cell phones meant that the third generation of digital communications. In 1995 came the first generation of digital mobile phones can only make voice calls; appeared in 1996 and 1997 the second generation digital mobile phones will increase the receive data functions, such as receiving e-mail or web page; the third generation of the main difference with the previous two generations voice and data in the transmission speed of the upgrade, it can handle images, music, video streaming and other forms of media services including web browsing, conference calls, e-commerce and other information services. Relative first-generation analogue phones (1G) and second-generation GSM, TDMA digital mobile phones, etc. (2G), 3G communication the name of the range, the ITU provisions of the "IMT-2000" (International Mobile Telephone 2000) standards, European Telecommunications giants claimed it as "UMTS" Universal Mobile Telecommunications System. The standard requires that, cell phones wholesale mobile terminal moves to speed, the transmission data rate of 144kbps, outdoor stationary or walking speed was 384kbps, while the interior is 2Mbps. But these requirements do not mean that users can rate can reach 2Mbps, because the room rate will also depend on the frequency of the building detailed planning and organization and close collaboration with the degree operators.

GPS positioning system for navigation GPS navigation system's basic principle is to measure the known location of the satellite to the user the distance between the receiver and then integrated multi-satellite data can know the exact location of the receiver. To achieve this purpose, the satellite's position can be based on-board clock time recorded in the satellite ephemeris identified. The user to the satellite's distance from the satellite signal transmitted through the record to the user the experience of time, and then multiplied by the speed of light received (due to the interference of the atmosphere ionosphere, this distance is not the user and the real distance between the satellites, but pseudorange (PR): When the GPS satellites normal working hours, will continue to use the binary 1 and 0 symbol consisting of pseudo-random code (PN for short) launched the navigation data. garmin gps using pseudo-code, a total of two, namely civilian C / A code and the military of the P (Y) code. C / A code frequency of 1.023MHz, repeat the cycle of a millisecond, the code distance between a microsecond, the equivalent of 300m; P code frequency of 10.23MHz, repeat the cycle of 266.4 days, Code spacing of 0.1 microseconds, equivalent to 30m. The P code Y code is formed on the basis of confidentiality better performance. gps navigator message including the satellite ephemeris, work status, clock corrections, ionospheric delay correction, atmospheric refraction amendments and other information. It is the solution from the satellite signal modulation out to 50b / s modulation at the carrier frequency on the launch. gps navigation message included in each of the main frame 5 sub frames for each frame size 6s. the first three frames of 10 characters each code; repeat every 30 seconds, updated hourly. After the two were 15000b. navigation data telemetry in the contents of the main code, the conversion code, the first 1,2,3 block, most important of which was ephemeris data. When the user receives the navigation data, the extraction of the satellite time and do it with their own clock compared satellite and the user will be aware of the distance, and then use the navigation data in the satellite ephemeris data, calculate the time of satellite launch message Office location, the user WGS-84 geodetic coordinate system of the position, velocity and other information can be informed. see gps system satellite component of the role is to continue to launch navigation message. However, the user receiver using the onboard clock with the clock not always synchronized, so in addition to the user's three-dimensional coordinates x, y, z, but also introduce a Δt is the time between the satellite and receiver differential as unknowns, and then four equations out of these four unknown solution. So If you want to know the receiver position, at least four satellites can receive the signal. Visit TradeTang.com.

GPS global system of development and prospects Global Positioning System (GPS) is 70 years of this century, jointly developed by the U.S. armed forces a new generation of space satellite navigation and positioning system. Its main purpose is to land, sea and air to provide three major areas of real-time, weather and global navigation services, and for intelligence gathering, surveillance and emergency communications, and other nuclear explosion of some military purpose, the United States an important component to dominate the global strategy. garmin gps After 20 years of experiments, a cost of 30 billion U.S. dollars, to March 1994, the global coverage of up to 98% of the 24 GPS satellite constellation has been laid to complete.

GPS systems can provide users with continuous real-time three-dimensional location information to determine the user's movement speed, and provide accurate timing service, the positioning error is less than 10 meters, timing error of less than 0.1 seconds, timing accuracy than 0.000001 seconds, and its radio signal also has a certain anti-interference ability. If I have the combat units of the gps system the location information transmitted by radio communication to the operational command center constantly, plus I reconnaissance by means of the acquisition of enemy targets in the location information, and then centralized in large screen displays to show District commanders can make me able to keep up on the two sides of the battlefield, the dynamic situation, and thus its operational command provides the basis for an accurate and important. Thus, military strategists since thousands of years, "Operations Research or defeat, decisive in the distant" dream is finally a reality is not it?
As the gps navigator possess all-weather, precision and automatic measurement of the characteristics, as advanced productivity measurement tools and new, has been integrated into the national economic construction, national defense and social development in various areas of applications. With the Cold War and the global economy booming, the U.S. government announced that from 2000 to 2006 period, from threats to ensure the U.S. National Anquan premise, the abolition of SA policies, GPS civilian signal accuracy improvement in the global context, using C / A codes from the point positioning accuracy of 100 meters up to 20 meters, which will further promote the application of GPS technology to improve productivity, operational efficiency, scientific level and quality of life, stimulate the growth of GPS market. Experts predict that in the United States, just a car gps navigation system, 2000 years later, the market will reach 3 billion U.S. dollars, while in China, the car navigation market will reach 5 billion yuan. Visible, GPS technology market prospect is very impressive.
