| 摘 要： | 由于MEMS陀螺精度低、漂移大,使得MEMS陀螺和加速度计构成的微惯性导航系统(Micro-INS)的精度很低,导航定位误差发散很快,不能满足载体进行导航定位定姿的要求.而相对MEMS陀螺,MEMS加速度计精度较高,据此提出用MEMS加速度计来构成的无陀螺微惯性导航系统(Gyro FreeMicroInertial N...

| Abstract: | Due to low precision and large drift of MEMS gyro,the navigation precision of micro inertial navigation system equipped with MEMS gyro and accelerometers is very low and its position error and attitude error could diverge quickly,so the vehicle's navigation requirement on position and attitude determination could not met.While the precision of MEMS accelerometer is higher than that of MEMS gyro,a gyro free inertial navigation system(GFINS) only with the MEMS accelerometer is proposed to replace the MINS sys... |
