| 摘 要： | 无陀螺捷联惯导系统采用加速度计来解算载体相对惯性系的角速度，从而代替角速度陀螺仪。考虑重力影响，对两种不同配置方式的6加速度计捷联惯导系统建立了载体运动参数解算模型，在此基础上提出了一种12加速度计配置方式，从而利用多传感器的冗余信息对算法进行优化，消除了角速度解算过程中求解微分方程带来的累积误差，提高了角速度解算精度。

| Abstract: | The angular velocity was computed using accelerometers instead of angular velocity gyroscopes in gyroscope-free strap-down inertial navigation system(GFSINS).The models for computing the parameters about the carrier motion of two kinds of 6-accelerometer configuration GFSINS schemes were established under considering gravitational effect.Based on this,a 12-accelerometer configuration scheme was proposed.The algorithm is optimized using the sensor redundant information and the accumulative error deriving from the solution of differential equations is reduced and the accuracy of the computed angular velocity is increased. |
