以地磁匹配导航原理为理论依据,设计了半实物仿真系统的总体方案。在半实物仿真模型选取和结构组成的基础上,系统分析地磁场数据库仿真、载体干扰磁场补偿、地磁场环境仿真和地磁匹配导航算法这4种关键技术并提出了相应的工程解决方案,为实现地磁匹配导航半实物仿真提供一种参考。

According to the principle of geomagnetic matching navigation, an overall scheme of hardware-in- the-loop simulation is proposed. Based on the model selection and structure of hardware-in-the-loop simulation, the key technologies of geomagnetic database simulation, carrier interference magnetic field compensation, geomagnetic environment simulation and geomagnetic matching navigation algorithm, are analyzed systematically, and the corresponding solutions are put forward, which provides a reference for the hardware-in-the-loop simulation.
