Abstract

This paper presents a tool for the numerical propagation of high-fidelity astrodynamics, called PHiFA. The coupled orbit-attitude dynamics for space objects are modeled by considering various types of perturbative forces and torques. Two methods have been implemented to calculate the surface forces: the area matrix method and the beam method. The beam method is more precise as it discretizes the source media (e.g., sunlight and aerodynamic wind) and the surface of the target into multiple rays and finite elements, respectively, and then accumulates the effect of each hit. The PHiFA tool was tested and validated using a 3U CubeSat model and the defunct European environment satellite (Envisat) model.

用于高保真天体动力学数值传播的工具

本文提出了一种用于高保真天体动力学数值传播的工具，称为PHiFA。通过考虑各种类型的微扰力和力矩，建立了空间物体轨道-姿态耦合动力学模型。计算表面力的方法有两种：面积矩阵法和梁法。光束法更精确，因为它将源介质（如阳光和空气动力学风）和目标表面分别离散为多个射线和有限元，然后累积每次撞击的效果。PHiFA工具使用3U立方体卫星模型和已失效的欧洲环境卫星（Envisat）模型进行了测试和验证。
