A self-organized integrated air-ground detection swarmis tentatively applied to achieve reentry vehicle landing detection,such as searching and rescuing a manned spaceship. The detectionswarm consists of multiple unmanned aerial vehicles （UAVs）and unmanned ground vehicles （UGVs）. The UAVs can accessa detected object quickly for high mobility, while the UGVs cancomprehensively investigate the object due to the variety of carriedequipment. In addition, the integrated air-ground detectionswarm is capable of detecting from the ground and the air *** accomplish the coordination of the UGVs andUAVs, they are all regarded as individuals of the artificial *** individuals make control decisions independently of othersbased on the self-organizing strategy. The overall requirements forthe detection swarm are analyzed, and the theoretical model ofthe self-organizing strategy based on a combined individual andenvironmental virtual function is established. The numerical investigationproves that the self-organizing strategy is suitable andscalable to control the detection swarm. To further inspect the engineeringreliability, an experiment set is established in laboratory,and the experimental demonstration shows that the self-organizingstrategy drives the detection swarm forming a close range and multiangularsurveillance configuration of a landing spot.

在轨运行的航天器表面形成损伤有可能导致严重的后果,需要对航天器进行在轨实时损伤检测。针对航天器损伤检测图像样本难以获取的问题,本文采用智能化检测方法,提出了一种用于航天器表面损伤样本扩充的生成对抗网络,该网络能够学习单张输入图像的特征纹理表示,从而生成大量与输入图像特征相似的细粒度尺度样本,实现了少量图像数据样本的扩充。利用YOLO目标检测算法在扩充的图像样本中进行表面缺陷与损伤的检测识别,获取了较高的检测精度,为未来航天器健康状态监测与评估、通用化服务机器人应用及太空原位建设等提供了技术支撑。

A Hardware-in-Loop Simulation System for Fractionated Spacecraft Cluster

引用

Journal of Aerospace Science and Technology 2015年第1期1卷 1-8页

作者： An Meiyan wang zhaokui Zhang Yulin School of Aerospace Engineering Tsinghua University Beij'ing 100084 China China Astronaut Research and Training Center Beijing 100093 China

FSC （Fractionated Spacecraft Cluster） is a kind of loosely distributed space system which is comprised of multiple physically independent spacecrafts orbiting closely and interactively communicating via wireless network. Spaceborne ad-hoc network, as the physical infrastructure for information exchanging, is one of the enabling technologies of FSC. The demonstration of FSC flying supported by ad-hoc network is worth for the sake of proving the rationality of FSC and seeking technological improvements. Considering this, a NNP （Network Node Prototype） for spaceborne ad-hoc network is developed in this paper, which transmits the information required by the FSC cooperation. Four NNPs are then built up and collaborated into a hardware-in-loop simulation system, in which a typical loose satellite cluster flying mission was performed. The simulation results showed that the NNPs can support the inter-satellite communication for satellite cluster flying.
