Research on a New Eight-Accelero meter Configuration for Attitude Angle Calculation of UAV

摘要

The scheme to calculate attitude angle of UAV was introduced to replace high-priced angular velocity gyroscope, so as to lower the cost of UAV. A new eight-accelerometer configuration for attitude angle calculation of UAV was proposed. It can optimize algorithm, remove accumulative error in process of calculation and improve calculation precision through multi-sensor redundant information. The digital simulation results show that attitude angle calculation can satisfy current requirements and has low calculation error and time accumulation, which is of practical significance to research on inertia device.
