Description
Technical field
The present invention relates to geosynchronous satellite mobile Internet service system, a kind of internet universal service system that designs for mobile traffic (as: steamer, train, automobile) of more specifically saying so.
Background technology
Today of information-intensive society, internet network has been penetrated into each corner of people's live and works.People catch sight of between careless, have left internet network and usually can't handle official business, can't amusement, can't exchange.And along with popularizing of network, this trend is still in accelerated development.
Though the internet is ubiquitous,, people but are difficult to enjoy this modern instrument in travelling.People attempt to go to solve this with diverse ways and regret.The service system that has come into operation at present has following two classes:
The first kind adopts terrestrial wireless network mode.One of its technical method is the surfing Internet with cell phone service system.People have developed the GPRS function that can surf the Net on second generation mobile phone.People also place high hopes to the 3G mobile in future.But the GPRS surfing Internet with cell phone is too slow after all, and price is expensive too, causes people to use seldom so far.Whether the 3G mobile network can begin to build in the immediate future, does not still have final conclusion at present.Even if 3G network builds up, according to present prediction, its cost of use also has been difficult to bigger decline.Another kind of technical method and service mode are " wireless broadband networks ".Present this network service begins to move in the big city.But this kind technology also needs to set up as the similar public access network of the cellular network of mobile phone, and user's meaning in office area is used.Set up the Radio Access Network as the covering whole city of mobile phone, need huge investment, therefore, cost of use is also higher.If it is want this service is generalized in the long-distance travelling, then difficult more.Because use this technology to set up to cover the network of national wide geographic area field, mountain area, the sea of city (especially away from), be a huge engineering that needs the astronomical figure capital input, not only be difficult in a short time realize, also may not be feasible from seeing economically.
Second class adopts the satellite radio network mode.In recent years, along with the development of satellite technology, people bring into use low-orbit satellite and medium earth orbit satellite to solve the difficulty of mobile communication.Low-orbit satellite and medium earth orbit satellite, comparatively speaking, apart from earth close together (low-orbit satellite is 700-1 apart from earth distance, and 500 kilometers, medium earth orbit satellite is apart from about 10,000 kilometers of earth distance).People can carry out communication with more small-bore antenna to satellite on the carrier that moves.On this basis, can make up the internet network service system.But owing to be not to adopt synchronous satellite, (low orbit satellite is more than tens to cover a large amount of satellite of whole earth surface needs; In about 10 on rail satellite), and synchronous satellite only needs about 3.The increase of number of satellite, the raising that brings cost, the also corresponding cost of use that improves the user, therefore, this kind Internet service mode is not popularized to masses so far as yet.
Summary of the invention
The objective of the invention is to overcome the weak point of above-mentioned two class service systems, a kind of with low cost, system is simple, reliable, user's relatively inexpensive service system easy to use and provide.
The present invention proposes to design a kind of system that is based upon on the high-power SYNCOM technology.Because the synchronous satellite use cost is lower, it can set up the internet network public service that use, relatively inexpensive for the user on prior art.Make public users on the steamer that moves, train, automobile, use the internet to become possibility at an easy rate.Because this system does not use the instrument of mobile phone as online, does not use existing wireless broadband network yet, therefore do not need to set up similarly " cellular network ", help cost saving.Simultaneously, this method has only the more satellite of use just can provide continual Communications service also unlike low-orbit satellite and medium earth orbit satellite, and therefore, cost is the end of than.If with this technology is that service system is set up on the basis, the service of development internet network, then user's use price can be very not high.But the realization of this system has the basis of two indispensabilities: 1) the regional covering communication satellite of high-power, high power capacity (as: China plans high-power, the big capacity communications satellite emission in 2005).If there is not this high-power communications satellite, the signal that then is transferred to ground too a little less than, be that effective isotropic radiated power (EIRP) is lower, receiving system must be equipped with large aperture antenna, this not only makes the price of service system rise, and large-scale antenna is difficult to be fit to the installation environment on the high-speed moving object, so also do not have feasibility on the engineering.This also is up to now, the main cause that can't set up based on the mobile Internet network service of synchronous satellite; 2) have the low price of dynamic auto tracking synchronous satellite ability in moving, the ground satellite station of miniaturized antenna.The key technology that realizes this kind ground station is low price, the miniature antenna system with automatic tracking capability.Traditionally this kind of antenna system need be based on the inertial measuring unit of precision, and the multidisciplinary technology such as radiotechnics, computer technology, automatic control technology that are used in combination comprehensively realize.The systems technology difficulty is big, and is bulky after realizing, costs an arm and a leg, and therefore is difficult to come into operation.This technology is along with the progress of new satellite antenna control technology in recent years, obtained successively to break through, and for example Chinese patent application number is a disclosed automatic tracking antenna system in 200410097189.7.Therefore, the key technology basis of realizing this kind service is ripe basically.So the present invention has possessed the possibility that realizes on engineering.
