Assisted Positioning System of Radar Wave Flow Measuring Instrument Based on STM32
The geospatial position of radar wave flow measuring instrument can not be obtained in the process of measuring cur-rent,In order to solve this problem,Introduced the Assisted positioning system of Radar Wave Flow Measuring Instrument based on STM32.The system collecte the speed and position data of GPS/INS in real time based on STM32,so as to realize the position-ing function of the instrument through integrated navigation.In the software,the anti-outlier Kalman filtering method is used to filter out the latitude and longitude information received by GPS,and adaptive Kalman filter alogrithm improves the practicabil-ity and accuracy of the system.The experimental results show that the system can obtain the spatial position of instrument,and the output position information is better close to the real trajectory,the positioning accuracy is within 0.5m,which can meet the posi-tioning requirements of Radar Wave Flow Measuring Instrument.
