A Measurement Methods for Angular Motion of Body Rotation based on Only-Accelerometer Coplanar Configuration

摘要

In the paper, an angular velocity measurement based on only-acceleration was proposed to deal with the problem that the angular motion of autobiography carrier could not be measured through gyro. Comparing the merit and demerit of traditional configurations, a new coplanar configuration of only-acceleration was designed based on the relativity between Vertical accelerometer and parallel accelerometer. Given the observing accelerometers selection principle, the angular motion measurement based on only-acceleration coplanar configuration was designed. Finally, according to the aerodynamic coefficients, simulation experiment was performed. And the result of the simulation was shown that, in the 180s time of flight, the angular velocity measurement error of this method was equivalent to 10(°)/h gyro drift.
