Abstract:

设计了一种基于RT-LAB的SINS/GPS/CNS(StrapdownInertialNavigationSystem/GlobalPositioningSystem/CelestialNavigationSystem)组合导航系统仿真平台方案,建立具有故障检测、隔离和系统重构能力的基于联邦卡尔曼滤波器的姿态、位置、速度组合导航系统方案和结构.将SINS与GPS的位置之差和速度之差作为SINS/GPS子滤波器的观测量,通过CNS给出的载体惯性姿态信息获得SINS的姿态误差角测量信息.仿真结果表明,该系统方案具有较强的容错性能、较高的导航精度和很强的实时性能,为组合导航技术的研究提供了有益的参考.
