Nettet21. des. 2024 · Despite the fact that accelerometers and gyroscopes are used in inertial navigation systems (INS) to provide navigation information without the aid of external references, accumulated systematic errors are shown in sensor readings on long-term usage. In this work, a new approach is proposed to overcome this problem, by using … NettetThe motivation of this research is to investigate the integration of PPP and our previous integrated result using low-cost IMU/SPEED sensors. This paper will describe the …
Low-cost PPP/INS Integration for Continuous and Precise …
NettetIntegrating a low-cost DF GNSS receiver with low-cost MEMS IMU performs with decimetre-level accuracy even in an obstructed environment when there are only three … Nettet15. feb. 2024 · Further enhancements of position RMS benefiting from the odometer are 1.34%, 1.41%, and 1.73% in the three directions. (2) Anyway, the accuracy of BSSD PPP/INS/Odometer tightly coupled integration is slightly higher than that of undifferenced PPP/INS/Odometer integration, with average improvement percentages of 7.71%, … michel sigallas naturopathe
