Problems solved by technology

[0002] In modern vehicle satellite navigation and positioning technology, satellite positioning technology is widely used, such as the global positioning system (GPS) of the United States, GLONASS of Russia, and Beidou positioning system of China; Loaded with a GPS receiver, if you can ensure good reception of 4 satellite signals, you can accurately know the vehicle's position, speed, direction of movement and other elements; but in practical applications, due to metropolitan viaducts, tunnels, overpasses and other reasons, many areas Satellite signals cannot be received; moreover, due to the multi-channel effect of radio waves brought by large urban buildings, the positioning accuracy of GPS is greatly reduced; in jungle areas or cities with tall trees, due to the influence of leaves on radio waves, in rainy days, GPS The positioning is unreliable; the consequence of this is that continuous and accurate vehicle positioning cannot be provided, which affects the use of satellite navigation systems; in the market, many companies provide standard GPS positioning modules; the GPS positioning module is just a circuit board, without a shell and Ordinary user interface, mainly used by GPS receivers and system integration manufacturers

Embodiment Construction

[0022] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the autonomous positioning part using inertial navigation technology and the power management of the product, the MCU central processing unit, and the embedded software system with enhanced Kalman filter algorithm are installed on one circuit board (called DR board), GPS OEM circuit board Installed on the upper part of the DR board, the power supply is obtained from the DR board through the standard interface of the current GPS OEM board, and the GPS positioning data is also provided to the DR board through the standard interface; the enhanced GPS OEM board data interface is installed on the DR, and this interface is compatible with the DR board. The standard GPS OEM board interface is compatible; this can realize the interchange between this module and the GPS OEM board.
