A Method for Numerical Simulation of Horizon Sensor Using STK
摘要
介绍了红外 地平仪探头的布局和姿态解算公式,然后提出了一种利用卫星工具包软件(Satellite Tool Kit, STK)建立地平仪仿真模型的方法。利用 该模型对地平仪进行了动态仿真并获取了探测图像。最后,利用获取图像解算出了卫星姿态并给出 了不同工况下的仿真结果。该方法可以在项目开发早期帮助确定地平仪方案,以避免不必要的 重复工作。
Abstract
The probe layout and attitude formula of an infrared earth sensor are presented. Then, a method for establishing the simulation model of the horizon sensor by using the Satellite Tool Kit (STK) is put forward. The established model is used for the dynamic simulation of the horizon sensor. The detection images are acquired. Finally, the satellite attitude is calculated by using the obtained images and the simulation results under different conditions are given. The method is helpful to the determination of the horizon sensor plan in the early phase of project development so that unnecessary repetition can be avoided.
