Description
Technical field
The utility model relates to navigator technical field, especially relates to a kind of Big Dipper command type subscriber computer.
Background technology
" Big Dipper " is Chinese autonomous Design, independent satellite navigation system of building, one of global navigation satellite location four large core supplier that Ye Shi relevant bodies of the United Nations are assert.
Beidou I navigation positioning system backs up in-orbit satellite, central control system, Calibration System and all types of user machine equipment by two geostationary satellites, one and forms.Geostationary satellite is called again space segment, and remainder is ground application system.Its principle of work: system adopts three ball intersection measurement principles to position, and take two geostationary satellites (location aware) as two centre ofs sphere, two centre ofs sphere to user's distance (measuring amount that native system will complete) is that radius is as two spheres; Another take the earth's core as the centre of sphere, the sphere that the user of take does as radius to the distance in the earth's core, and three ball plotted points are user's position (getting rid of mirror point while resolving).Two satellites of take are the centre of sphere, and the satellite of take can be made two balls to the distance of measuring point as radius.After two spheres intersect, its intersection is a great circle, is referred to as intersection circle.Intersection circle and the earth respectively have an intersection point in the Southern Hemisphere and the Northern Hemisphere of the earth after intersecting, due to the service area of system on the Northern Hemisphere, the mirror point in the eliminating the Southern Hemisphere, can determine the coordinate position of measuring point.
No. two (BD-2) global position systems of the Big Dipper are new generation satellite navigation systems that China independently develops, and plan is comprised of five satellites and 30 non-geo satellites, and this system has formally been set up the project in 2004 and started and built.In system, the Galileo during BD-2 builds with the GPS of the U.S., Muscovite GLONASS and European Union is the same, belongs to RNSS(Radio Navigation Satellite System).BD-2 satellite navigation system is comprised of ground segment, space segment and user segment, adopts CGS2000 coordinate system, is system time reference while take the Big Dipper.The same with other navigation positioning system, all functions of BD-2 system finally all realize by subscriber equipment, so subscriber equipment is an important component part of BD-2 system.
The key distinction of No. two (BD-2) global position systems of the Big Dipper and Beidou I navigation system is: Beidou I navigation system belongs to regional service system, and number of satellites is few, and orbit altitude is high, and locator meams is active location, has communication function; No. two satellite navigation systems of the Big Dipper are global service system after all building up, and navigation principle and GPS are similar, and number of satellites many (35) can realize passive location, without communication function.
Tradition Big Dipper command type subscriber computer is generally arranged on battery in lower cover, changes the lower cover that battery need to be taken complete machine apart, dismantles more inconveniently, and in disassembly process, easily causes the pollution of miscellaneous part.
Utility model content
The technical matters that the utility model solves is to provide a kind of Big Dipper command type subscriber computer, the utility model is the auxiliary products of No. two satellite navigation systems of the Big Dipper, after No. two satellite navigation systems of the Big Dipper are all built up, and nearly 35 of number of satellites, can realize passive location, without communication function.The utility model is simple in structure, cheap for manufacturing cost, corrosion-resistant; Facilitated installation and the maintenance of complete machine main body, battery disassembly and assembly is convenient, without the lower cover of taking complete machine apart, only need take battery cover board, i.e. replaceable battery apart; The utility model can independently be put use, is applicable to standard 1U rack and installs.
