| 摘 要： | 本文研究了采用低精度陀螺的航向姿态基准系统(AHRS),应用卡尔曼滤波技术与全球定位系统(GPS)组合所构成的导航系统。文中推导了组合导航系统的动态方程,给出了该系统在航空应用中,采用S形机动飞行实施空中对准的协方差模拟结果。分析结果表明,该组合系统能提供较高精度的导航与姿态信息,具有较大的实用价值。

| Abstract: | This paper discussed the GPS-AHRS integrating navigation system with low accuracy gyroscope. The dynamic equations of the integrating system are derived. Under the aeronautical condition, a covariance analyses of the integrated system performance was conducted with maneuvers of the S-shape trajectory.The results of the covariance analysis indicate that the integrating system can provide higher navigation accuracy and is worthful in wide application. |
