Description
Technical field
The utility model relates to Timing Receiver field, relates in particular to a kind of control module based on big-dipper satellite and GPS bimodulus group conversion Timing Receiver.
Background technology
Along with " three-step-march " of Beidou satellite navigation system disposed, come into effect, this emerging technology of satellite navigation is more and more subject to the favor of all trades and professions.The world today upper one co-exists in four large GPS (Global Position System), comprising the GPS of the U.S., and Muscovite GLONASS, the Galileo of European Union and Chinese Beidou satellite navigation system.Except these four Global Navigation Systems, also have Countries carrying out local satellite navigation system or Navsat enhancing system, in order that meet hi-Fix and the navigation application of this country or surrounding area, this has wherein just comprised the WASS of the U.S., the GAGAN of India and Japanese QZSS etc.The gps satellite navigational system of the U.S. is walked in the prostatitis of each large system, is also the navigational system that the whole world is most widely used.Along with the U.S., in 2000, the public has been cancelled after SA interference, ground GPS equipment develops just as blowout shape, GPS equipment is constantly penetrated into each corner in people's life, now successful Application, in fields such as military affairs, traffic, electric power, security protection, time services, becomes the national global strategy infrastructure of the U.S..
GPS and the Muscovite GLONASS of the contrast U.S., the Beidou satellite navigation system of China is started late.China started to open the service of Beidou satellite navigation pilot system in 2000, this system is different from the Passive Location Principle of GPS, adopt double star active location pattern, and there is short message communication function, successfully be applied in the numerous areas such as mapping, telecommunications, water conservancy, fishery, communications and transportation, forest fire protection, the mitigation disaster relief and national security, for China's development Beidou satellite navigation system has been carried out sufficient technology and market place mat.Be accompanied by the lift-off of the 4th Big Dipper Navsat June in 2010, China announces that autonomous Big Dipper positioning system has formally entered the intensive space networking stage, and plan before and after 2012, to open the satellite navigation positioning service to the Asian-Pacific area, in the year two thousand twenty, reach global signal covering power.
Now, the important events that China is much related to national security still adopt GPS as main navigation means and time service means.Although promising to undertake, the U.S. will forever unremittingly provide civil navigation signal and silent approvement to exempt from patent royalties, what but we should regain consciousness recognizes, satellite navigation, as the great infrastructure of country of the army and the people's double attribute, all has great and wide influence power to national Major Strategic interests such as infrastructure, economic security, national defense and military and international statuses.Once be in an emergency or vital interests conflict, national defense and military or socio-economic security all will be subject to elbow processed and even coerce, and this will be heavy on the impact of national interests.When the time comes, to adopt GPS be main time service field will even paralyse because cannot obtain the confusion of working of unified time as: electric system, financial instrument system, mobile communication system.Communications and transportation, personnel etc. may can not rush towards urgent place the very first time because obtaining location-based service accurately.Large quantities of armies assemble deployment and also there will be problem, and precision guided weapon will lose bright eyes.If such thing occurs, and will be huge on the impact of China.What country and relevant department were very clear-headed has recognized this problem, clear and definite proposition autonomous construction Beidou satellite navigation system, and the input of lasting for years, will soon have built triones navigation system first stage of the project in 2012.Predictable arriving, in several years of future, the industry that is related to national security will be popularized Big Dipper navigation application at first, ensure the safety of national product life and stablize.Through after the scale Demonstration Application of each professional industry, will spread to gradually mass consumption class market, finally become the GPS (Global Position System) of running neck and neck with GPS, create the considerable output value.
In sum, provide a kind of and both can carry out time service by big-dipper satellite, also can be necessary by the time service machine of GPS time service, the control module in time service machine is to need improved emphasis.
