Simulated GPS IF and IMU signals and verification

  • 摘要: 为了研究GPS/INS(Inertial Navigation System)组合导航方案和算法,设计了一种GPS中频信号和IMU(Inertial Measurement Unit)信号的软件模拟器.首先建立了载体的运动模型,然后介绍了信号的仿真方法.根据载体的运动产生IMU信号,载体的典型运动包括平飞运动、横滚运动、俯仰运动和偏航运动.建立了典型的干扰模型,包括欺骗式干扰和压制式干扰(窄带干扰、宽带干扰、连续波干扰和锯齿调频连续波干扰等4种),实现了干扰环境下的场景模拟.GPS/INS组合导航软件接收机对模拟器输出的数据进行解算,结果表明:信号的仿真算法是正确的,模拟器可以为组合导航接收机提供有效的中频信号和IMU信号.
