Description
Technical field
The utility model relates to antenna installation, is specifically related to a kind of multifrequency Big Dipper antenna.
Background technology
China's Beidou satellite navigation system (BeiDouNavigationSatelliteSystem, BDS) is the GPS that China develops voluntarily. It is the 3rd ripe satellite navigation system after american global positioning system (GPS), Russia's Ge Luonasi satellite navigation system (GLONASS). Beidou satellite navigation system (BDS) and GPS of America, Russian GLONASS, European Union GALILEO are the suppliers that the satellite-navigation council of United Nations has been assert. The U.S. and the monopolization of Russia's station-keeping system have been broken in the foundation of China's Beidou satellite navigation system, can be the dual-use market of China and provide satellite navigation system Service assurance.
The feature of Big Dipper generation system is active location, authorization service, short message communication function. Active location refers to that user needs first to signal to satellite, and application location, by signal forwarding to terrestrial station after satellite reception, tells its position again by terrestrial station after calculating. This kind of relay type positioning service time is relatively long, and the number of users that satellite can provide for every second is limited in 540,000 people. Due to this kind of restriction, Chinese development Beidou II satellite navigation system. Beidou II system is in formally project verification on August 31st, 2004, and on April 17th, 2007 launches test satellite, provides trial run service on December 27th, 2011.
The transmitting-receiving frequency of a Big Dipper generation is L and S frequency range, and the reception frequency range of Beidou II is B1, receives terminal and need to support multiple frequency. Supporting the reception terminal antenna of multifrequency, existing solution adopts different antennas to receive respectively, the way of Zai He road signal. The way of the multiple antenna of multiple frequency, causes terminal volume to increase, and is inconvenient to the phenomenon carried, and hinders widely using of multifrequency Beidou satellite navigation system.
