摘要

本文探讨了如何在空间飞行任务中实施大规模分布式微小卫星网络，旨在为显示时间和空间依赖性的变量建立空间环境模型。本文介绍了用于时空解卷积的分布式传感理论，并描述了用于系统评估的性能参数。在存在磁场扰动的情况下测量低地球轨道的磁场被选为在模拟中演示这一概念的案例研究。为模拟空间环境而设计的超小型卫星群展示了传感中的时空解卷积能力。通过模拟任务，确定并讨论了自由飞行传感器群的设计和部署所面临的挑战，特别是在飞小卫星质量范围内。

Stochastic monitoring of the space environment with femtosatellite swarms

This paper is an exploration of how massively distributed femtosatellite networks can be implemented in space missions aimed at modelling the space environment for variables that show both time and space dependence. A theory of distributed sensing for space-time deconvolution is presented and performance parameters for system evaluation are described. Measurement of the magnetic field in low Earth orbit, in the presence of field perturbations, is selected as a case study for demonstrating the concept in simulation. A femtosatellite swarm, designed for the simulated space environment, shows the capability of space-time deconvolution in sensing. From the simulated mission, challenges in the design and deployment of free-flying sensor swarms, especially in the femtosatellite mass range, are identified and discussed.
