在德国航空航天中心与不莱梅大学应用空间技术和微重力中心的合作研究中，正在开发高性能卫星动力学模拟器。模拟器被组装为模拟模块、函数和实用程序的库，并按主题分组为子库。单个子库包含动力学模块，用于计算重力、大气、磁场、太阳压力、日食、星历表的环境模型，以及用于预先计算表面力和扭矩的预处理工具。还提供了一个转换库，包括日期和坐标转换以及几个数学函数。此外，正在开发一套简单的致动器和传感器模型。所有模块均可用于MiL（模型在环）和SiL（软件在环）应用，还有几个模块可用于HiL（硬件在环）环境。模拟器项目的出现是为了避免重新开发，从已经使用的工具中受益，并通过反复出现的问题陈述进行验证，并建立在现有知识的基础上，以应对新的挑战。本文详细描述了模拟器库的内容，并说明了所选用例的应用程序。
In a collaborative research effort between the German Aerospace Center and the Center of Applied Space Technology and Microgravity, University of Bremen, the high performance satellite dynamics simulator (HPS) is being developed. The simulator is assembled as a library of simulation modules, functions and utilities, thematically grouped into sub-libraries. The single sub-libraries contain modules for dynamics, environmental models for the calculation of gravity, atmosphere, magnetic field, solar pressure, eclipse, ephemerides, and preprocessing tools for the pre-calculation of surface forces and torques. A transformation library including date and coordinate transformations and several mathematical functions are also provided. Furthermore, a basic set of simple actuator and sensor models is being developed. All modules can be used in MiL (model-in-the-loop) and SiL (software-in-the-loop) applications, and several modules are ready for use in HiL (hardware-in-the-loop) environments. The simulator project has emerged from the desire to avoid re-development, benefit from tools that are already in use and have been validated for recurring problem statements, and build up upon existing knowledge for new challenges. This paper describes the simulator library content in detail and exemplifies application for selected use cases.
