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.
[0024] The size of the module i...
