摘要：
At present, the measurement range of micro gyroscope is limited and can not be applied to axial angular rate measurement of high rotation vehicle. Three inertial measurement schemes using dimension effect of accelerometers for the axial angular rate test and two-axis gyroscope for the yaw and pitch angular rate measurement were presented. Based on the random error formulas of function, the error transfer formulas of acceleration at the vehicle mass center and axial angular rate were provided which were helpful to select sensors and form the measurement system. The simulation result indicates that three schemes can be applied to attitude measurement of high rotation vehicle when the measurement range of micro gyroscope is limited. The second scheme that the inertial measurement unit is constituted by 4 accelerometers and 1 two-axis gyroscope should be chose preferentially.
