The invention relates to a compass / GPS (global positioning system) and INS (inertial navigation system) combination vehicle navigation positioning system based on a GIS (geographic information system) technology. The combination vehicle navigation positioning system consists of four parts, namely a second-generation compass-GPS, an INS, a GIS and a data fusion and control system, wherein the INS comprises a fiber-optic gyroscope, an acceleration sensor, a pressure sensor, an electronic compass, a reshaping circuit and an interface circuit which is connected with the data fusion and control system; the data fusion and control system comprises a processor and an interface; the processor is integrated with a Kalman filtering module. By the research and development of a real-time, stable and high-accuracy second-generation compass / GPS and INS combination vehicle navigation positioning system based on the GIS technology, a vehicle second-generation compass and a GPS navigation positioning terminal are compatible and are combined with the INS, a user can receive a second-generation compass signal and can also receive a GPS signal, compatibility and automatic mutual switching are realized, and the accuracy and reliability of navigation positioning are improved.
Description
Technical field: [0001] The invention relates to the field of vehicle navigation technology, in particular to a GIS technology-based Beidou / GPS and INS combined vehicle navigation and positioning system. Background technique: [0002] The global satellite navigation system began in the 1970s with GPS in the United States. Its application is becoming more and more extensive, and it is very important to the country's economy and national defense. The European Union predicted more than 10 years ago that if satellite navigation is interrupted for one day, the economic loss will exceed 1 billion euros. If the loss is evaluated now, the amount may be doubled. For political and military purposes, intentionally shutting down or reducing the accuracy of navigation and positioning in an area will cause chaos and losses that will be incalculable. Secondly, the GPS system in the United States has developed to this day, and its annual output value has reached tens of billions of dollars...
