The sensor imaging simulation method can not obtain the imaging results of the satellite sensors at a given time and corresponding orbit quickly and intuitively. The simulation method based on virtual reality is used to simulate the on-orbit imaging of optical-earth observation satellites in real time, and the virtual space environment According to the imaging model of the sensor, the satellite sensor is mapped into the virtual space environment to realize satellite on-orbit imaging simulation, and the imaging error model is added to complete the imaging simulation. The experimental results show that the proposed method is fast and effective and can provide simulation data for related research, which lays the foundation for full-link dynamic real-time remote sensing simulation.
