摘要：近年来，空间变得更加拥挤，竞争更加激烈，特别是在低地球轨道，因此需要低延迟能力，以提供精确的轨道知识和准确的空间态势感知信息。本文研究了低地球轨道驻留空间物体（RSO）通过铱卫星通信网与地面操作员或用户进行连续通信的可行性。由于问题的复杂性和计算所需的时间，一个测试行业的技术，称为实验设计的实施，以有效地研究通信链路的可行性。具体地说，采用最优响应面法设计轨道参数的计算测试矩阵，并在DesignExpert中使用Systems Tool Kit进行仿真。结果提供了一个统计多项式模型，用于预测在指定的轨道参数下的总铱网络访问时间和窗口。初步评估和物理限制提供了模型空间包络，包括讨论如何在模型预测空间内表示具体轨道参数。
Abstract : In recent years, space has become more congested and contested, particularly in low Earth orbit (LEO), generating the need for a low-latency capability to provide precise orbital knowledge and accurate space situational awareness information. This thesis investigates the feasibility of resident space objects (RSOs) in LEO communicating continuously with ground operators or users through the Iridium Satellite Communications Network. Due to the problem's complexity and required time for computation, a test-industry technique called Design of Experiments is implemented in order to efficiently study the feasibility of the communication link. Specifically, an optimal response surface method is chosen to design the computation test matrix of orbital parameters in Design Expert for simulations using Systems Tool Kit. The results provide a statistical polynomial model for predicting the total Iridium-network access times and windows under specified orbital parameters. Initial assessments and physical constraints provide the model-space envelope, including a discussion on representing specific orbital parameters within the model prediction space.
