Abstract This work focuses on the nominal design and later maintenance of satellite constellations based on the 2D Necklace Flower Constellations for their application in Earth observation missions. To that end, we introduce a generalization of the 2D Necklace Flower Constellations formulation to adapt the methodology to constellations whose satellites have different mission requirements, while still allowing to reduce the searching space in satellite constellation design. Moreover, this design is combined with its dual distribution in the Earth Centered–Earth Fixed reference frame to obtain additional information about the dynamic of the system, including the sub-satellite point revisiting time, or the relative to Earth distribution. This is used to optimize the constellation in terms of maximum uniformity of the distribution with respect to the Earth. Finally, a detailed example of application of this design methodology is presented, where a constellation based on satellites with different mission requirements is considered.

应用于地球观测任务的二维项链花星座

摘要 这项工作的重点是基于二维项链花星座的卫星星座在地球观测任务中的标称设计和后期维护。为此，我们介绍了 2D Necklace Flower Constellations 公式的泛化，以使该方法适应卫星具有不同任务要求的星座，同时仍然允许减少卫星星座设计中的搜索空间。此外，这种设计与其在地心-地球固定参考系中的双重分布相结合，以获得关于系统动态的额外信息，包括卫星点重访时间或相对于地球分布的信息。这用于在相对于地球的分布的最大均匀性方面优化星座。最后，介绍了该设计方法的详细应用示例，其中考虑了基于具有不同任务要求的卫星的星座。
