| 摘 要： | 运用四子样圆锥补偿现代捷联惯导系统姿态算法、针对船舶的摇摆运动在数字信号处理芯片（DSPs)上进行了仿真，并与三子样圆锥补偿算法，三子样等效转动矢量法和单子样毕卡逼近法的仿真，并与三子样圆锥补偿算法、三子样等效转动矢量法和单子样毕卡逼近法的仿真结果进行了比较。结果表明：四子样圆锥补偿能更有效地抑制不可交换误差，提高姿态精度，且整个导航算法在TMS320C6211 EVM仿真器上运行，所花时间为5．3毫秒。

| Abstract: | A four-sample coning compensation for the modern SINS attitude algorithm is simulated in the digital signal processor under the condition of swaying motion, and compared with a three-sample coning compensation, an three-sample equivalent rotation vector, and an sample Peano-Baker approach. The simulating results demonstrate that the four-sample coning compensation algorithm is much efficient in increasing the attitude accuracy by restraining the noncommutativity error. The whole navigation computation takes 5.3 millisecond in the TMS320C6211 EVM. |
