First, a brief review The application of satellite communications in our time not too long, is 70 years from the beginning of the 20th century, only 30 years. With the rapid development of satellite communication technology, satellite earth station equipment is gradually becoming smaller, satellite earth station antenna diameter reduced by a few tens of meters to 10 meters or meters. VSAT satellite communication system in this country more and more extensive application of all walks of life. (1) 1993 8, the State Council issued Document No. 55, explicitly provides for domestic VSAT satellite communication services to the community to set aside as operating one of nine telecommunications services, opened to the operation, and the business license system introduced on the use of VSAT communication services management and marketing operations made clear the provisions of acts, from the beginning of domestic VSAT satellite communications business into the telecommunications bu siness in China market and for the development of China's wireless paging communication with the entire the rapid development of telecommunication services market has played an important role. (2) as the basis of China's telecommunications network and mobile communication and the rapid development of data communications, wireless paging services continues to decline, domestic VSAT communication services in voice communication, the role of narrow-band data communication decreases, combined with higher operating costs, VSAT communications, many enterprises in poor condition, the development of domestic VSAT communication service market more difficult. Since 1998, Ministry of Information Industry market conditions at that time conducted a macro-control. During this period, there are some old enterprises have pulled out of VSAT VSAT communications, there are a number of new private enterprises have entered the field of VSAT communications, such as in 2003, 40 enterprises have be en 19 private enterprises, private enterprises enterprises accounted for 47.5% of the total, increased the proportion of private enterprises for the development of China's VSAT communications market has brought a new vitality. In addition the composition of VSAT way users of the tremendous changes have taken place in 2003, 35 have been put into operation enterprises, VSAT way users a total of 35,000, of which one-way data for the 26,000 small station, accounting for 76% ; two-way data for the 8,000 small station, accounting for 23.6%; voice small station was reduced to 104, accounting for 0.3%. VSAT communications applications from changes in the trend shows a one-way VSAT data services have become the backbone of business enterprises. (3) VSAT satellite communications market in China to maintain stable development. In 2001 a total of 33 enterprises completed 650 million yuan revenue. In 2002 a total of 40 enterprises completed 830 million yuan revenue, up 27.9% over the pre vious year. From the 2003 National VSAT communications business performance showed a total of 35 enterprises to complete VSAT revenue 1.07 billion yuan, up 28.9% over the previous year. Judging from the development of the last three years, the National VSAT service revenue growth of enterprises in more than 20%, higher than other communications. Therefore, generally speaking, VSAT satellite communications market in China still maintains a steady growth trend. Recent years, with China's rapid development of VSAT communication services, satellite remote applications, broadband data broadcasting, broadband data communications, satellite communications technology consistent with the characteristics and advantages of the continuous emergence of new business, to the VSAT satellite communication services operating units provide a good market opportunity, many business units to find their own market position, adjusted the company's business development strategy to enable enterprises to continuously improve operational efficiency. At present, China VSAT satellite communications services market and effective competition in the situation has taken shape, but from the norm and mature there is a certain gap between market requirements. In terms of funding, business development or operating mechanisms, VSAT enterprises still have a long way to go. Second, our prospects for satellite communication applications With the continuous development of satellite communication applications, satellite communications have been deep into all aspects of society, satellite telecommunications and broadcasting in the whole national economy will become increasingly prominent role in national economic development needs of satellite communications broadcast strong support to address the imbalance in regional economic development needs the support of satellite communications and broadcasting, satellite communications, sustainable economic development requires an important contri bution to radio. 1. Commercial applications (1) TV broadcast business Biggest advantage of satellite broadcast is limited only to use 1 to 2 satellites, can be an unlimited number of households to live a hundred of television programs, operating costs are so low that a live television business in China has tremendous development potential and good prospects. Currently in Europe, the United States, Japan has developed very well, China is in the planning and preparation stages of implementation. A vast territory, islands, mountains and minority areas and more populous but uneven distribution of cable television network developed. Therefore, China is the most suitable for the development of national satellite television broadcast, the world has such a huge market a few countries. 2010, China will be at least 13 to 14 billion people, 3 to 4 million households. If you have 1 / 10 off the family installed satellite TV receivers, satellite TV receivers each at a price equivalent to standard cable television fees calculated, then the five years 2006 to 2010, the satellite TV receiver industry output will reach 1200 ~ 2000 billion; monthly rent per home if the calculation of average annual income of 100 yuan will reach 400 billion yuan. Even without considering the development of satellite TV broadcast TV industry, computer industry, advertising, film and television industry, commerce, information industry and other satellite television-related development of tertiary industry brought about by the indirect benefits (estimated at less than 200 billion dollars), only the satellite television broadcast to the development will also open up a country as much as color TV, VCR and refrigerator industrial-scale new industries for the national economy each year an estimated additional 70 billion yuan of output value, increase the number of dozens of jobs million. Can predict that by 2010, well-off Chinese ordinary working families and rich peasant family, maybe not every family can afford cars, but at least 1 / 10 of the families have the ability to install satellite receiver machine. This potentially huge market rush that many western industrial countries. If the Chinese occupation, they do not take the initiative, not to advance the development, but as the current VSAT, GPS receiver market as exclusive to Western countries, will lead to huge losses. More importantly, satellite television with close ideological and spiritual civilization, if we ourselves do not make colorful, healthy and civilized television to occupy this position, then the West and neighboring countries and regions of the satellite TV will be multiple forms of penetration to the Chinese mainland.
