 Based on the requirement that high-accuracy geomagnetic field environment simulation are needed in the hardware-in-the-loop simulation of geomagnetic navigation, the system is established to simulate the geomagnetic field intensity. A lot of experiments have also been done. These experiments are associated with magnetic field free space, accuracy and real-time performance of the system. The results show that magnetic field free space is essential, a geomagnetic shielding canister can be used to shield geomagnetic field effectively, and the system can simulate the real-time geomagnetic field intensity of the flight path accurately. These experiments have proved that the system can provide an authentic geomagnetic field simulation environment for the hardware-in-the-loop simulation of geomagnetic navigation.
