Design of Beidou high precision positioning terminal based on ARM
Abstract：Critical infrastructure and security fields, including emergency rescue, industrial agriculture, personnel management and military security, the performance requirements of technical equipment are extremely strict, there is an urgent need for high-precision positioning technology to ensure the accuracy and effectiveness of operations, and special emphasis on the portability, miniaturization and low power consumption of equipment, in order to effectively solve this problem, A high precision positioning terminal device is designed. The device is composed of STM32F401RCT6 microprocessor, TAU1202, WH-GM5 and power module. The dual-frequency multi-mode positioning function of the positioning chip has good multi-path anti-suppression ability. By analyzing the navigation message data and sending it to any system platform conforming to the network communication interface through WH-GM5 communication module, STM32 achieves sub-meter average positioning accuracy in static mode. The software design is implemented on Keil platform. It has excellent positioning effect in practical application and has practical significance for engineering application.
