| 摘 要： | SINS/GPS组合导航系统能够实现在高动态和强电干扰的环境下实时、高精度的导航定位,为卫星的自主定轨提供了一种切实可行的方法。通常的SINS/GPS组合导航算法都是在地理坐标系下建立的。针对卫星的特点,着重研究了基于地心惯性坐标系,位置、速度组合模式的SINS/GPS组合导航算法,建立了该坐标系下组合导航系统的状态方程和量测方程,并进行了相关数学仿真验证。仿真结果表明,该SINS/GPS组合导航系统能较准确地给出卫星的位置、速度信息,适于卫星的自主定轨。

| Abstract: | The SINS/GPS integrated navigation system can implement real-time and high accuracy navigation in high dynamic and strong electricity environment,so it provides a feasible solution to autonomous orbit determination. Usually the algorithm about SINS/GPS is constituted in geography coordinate system.Considering the satellite characteristic,the paper studied the S/NS/GPS algorithm in position/velocity combination mode based on geocentric inertial coordinate system,and established state equations and measurement equations in this system.The associated computer simulation shows that the SINS/GPS integrated navigation system can precisely provide the satellite's position and velocity information,and can be applied to the satellite autonomous orbit determination. |
