Abstract

The invention discloses a small, light and low-cost integrated navigation system device, which comprises a master control MCU, a precise micro MEMS IMU sensor module, a high-precision GNSS module, a power supply module and a plurality of user interfaces, wherein the precise micro MEMS IMU sensor module, the high-precision GNSS module and the plurality of user interfaces are all electrically connected with the master control MCU, and the power supply module provides power for the master control MCU, the precise micro MEMS IMU sensor module, the high-precision GNSS module and the plurality of user interfaces. According to the invention, the high-performance and high-dominant-frequency Cotex-M7 kernel master control MCU is adopted, the peripheral circuit is simple, an ARM-level high-end chip with a complicated design in the past is replaced, the cost and the area of a PCB (Printed Circuit Board) are saved; meanwhile, a remote control system in the field of automatic driving is adopted to obtain differential information of the base station, so that the positioning precision of the combined navigation system is improved; and the plurality of user interfaces are provided, so that users can select at will, and the product compatibility is improved.

Description

technical field [0001] The invention relates to the technical field of an integrated navigation system, in particular to a small, light, low-cost integrated navigation system device. Background technique [0002] In the field of automatic driving, positioning devices and integrated navigation systems are currently on the market with large volumes and are not easy to install in passenger cars. At the same time, they also have built-in communication modules to obtain differential data from reference stations. However, in large automatic driving systems, It includes the function of remote Internet access. The built-in communication module can obtain the differential data of the base station, and input the differential data to the integrated navigation system through the user interface. Therefore, the remote communication module in the current integrated navigation system is not needed. At the same time The main control MCU uses a high-frequency Cortex-M7, and does not use high-...
