The output end of the embedded computer is connected with a liquid crystal displayer. The input end of the embedded computer is connected with an operation panel. According to the embedded vehicle-mounted navigation system based on the GPS or DR, the GPS is combined with the DR, the effectiveness, integrity and precision of the system are improved, and the embedded vehicle-mounted navigation system has the advantages of being comprehensive, all-weather, free of shielding and high in precision and has the good application prospect.
Description
Technical field
The present invention relates to the field of GPS, especially a kind of embedded navigation system based on GPS or DR.
Background technology
GPS (GPS) is U.S.'s second generation Radio Satellite navigation positioning system, it can provide navigation, location and time service information global, round-the-clock, in real time, but it requires there is direct its normal function of observability competence exertion to satellite., even simply there is " losing star phenomenon " in the traffic environment feature in view of Chongqing, mountain city self: when running into urban skyscraper thing, boulevard, viaduct and culvert tunnel etc., the signal quality of the Navsat that GPS receives can decline significantly.This make to be used alone GPS carry out navigator fix can not continuously for moving vehicle provides navigator fix information.Therefore have employed combined orientation technology to solve the problem.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned middle Problems existing, provide a kind of embedded navigation system based on GPS or DR.
The technical solution adopted for the present invention to solve the technical problems is: a kind of embedded navigation system based on GPS or DR, comprise data interface circuit, GPS-OEM plate, embedded computer, output terminal and the data interface circuit of described GPS-OEM plate are electrically connected, the output terminal of data interface circuit is connected with embedded computer, the output terminal of embedded computer is connected with liquid crystal display, and the input end of embedded computer is connected with guidance panel.
The input end of described data interface circuit is connected with odometer.
The input end of described data interface circuit is connected with angular rate gyroscope.
The invention has the beneficial effects as follows: described a kind of embedded navigation system based on GPS or DR, GPS and DR is combined, improve the validity of system, integrality and precision, there is comprehensive, round-the-clock, unobstructed, high-precision feature, have a good application prospect.
